INTERFERENCE ANALYSES

[EXTRACT FROM INTERFERENCE ANALYSES SECTION OF TECHNICAL STATEMENT ATTACHED AT EXHIBIT 51.]

THREE FULL-SERVICE DTV STATIONS (KRCA, KAJB, AND KFRE-TV) WERE IDENTIFIED BY THE TV_PROCESS PROGRAM AS REQUIRING STUDY FOR POTENTIAL INTERFERENCE FROM THE PROPOSED DTS NETWORK. OF THESE, THE PROGRAM REPORTED THAT THE PROPOSAL CAUSES NO INTERFERENCE WITH RESPECT TO ONE OF THEM (KAJB). FOR ONE OF THEM (KFRE-TV), IT SHOWED ZERO ADDITIONAL PREDICTED INTERFERENCE WHEN RADIATION TO STUDY CELLS WAS CALCULATED USING THE FCC METHOD THAT DEPENDS UPON HEIGHT ABOVE GROUND LEVEL (AGL), AND IT RETURNED A MINUSCULE RESULT (0.0007 PERCENT) WHEN ANTENNA HEIGHT ABOVE MEAN SEA LEVEL (AMSL) SERVED AS THE BASIS FOR INTERFERENCE CALCULATIONS.

THAT LEAVES ONE STATION (KRCA) TO ADDRESS. IN TABLE 1, IN WHICH THE ANTENNA AGL VALUES ARE USED BY THE TV_PROCESS SOFTWARE (I.E., USING THE FCC DEFAULT METHOD), THE PROGRAM INDICATED AN IMPERMISSIBLE LEVEL OF 2.0657 PERCENT NEW INTERFERENCE. IN TABLE 2, WHERE ANTENNA HEIGHT AMSL IS APPLIED, AN EVEN HIGHER LEVEL OF NEW INTERFERENCE, 2.8242 PERCENT, IS PREDICTED THAN SHOWN IN TABLE 1 FOR THE SAME FACILITIES. SUPPLEMENTARY STUDIES SHOWED THAT THE ADDED INTERFERENCE BEYOND THE 0.5 PERCENT THAT IS PERMISSIBLE IS ALL DUE TO THE TRANSMITTERS AT OAT MOUNTAIN DTS SITES 3 & 4. IT CURRENTLY IS ANTICIPATED THAT KRCA WILL JOIN KNBC IN USE OF THE OAT MOUNTAIN FACILITIES, COLLOCATING ITS OWN DTS TRANSMITTER(S) THERE, WHICH WOULD EFFECTIVELY ELIMINATE THE ADDED INTERFERENCE. A LETTER FROM KRCA AGREEING TO ACCEPT THE INTERFERENCE TO SIGNALS FROM ITS CURRENT MT HARVARD FACILITIES AND INDICATING ITS INTENTIONS TO JOIN IN THE OAT MOUNTAIN OPERATION IS EXPECTED TO BE PROVIDED SHORTLY. IF SUCH A LETTER IS NOT FORTHCOMING IN A REASONABLE TIME PERIOD, THEN THIS APPLICATION WILL BE MODIFIED TO REDUCE THE INTERFERENCE LEVEL TO KRCA SO THAT IT FALLS WITHIN THE PERMISSIBLE LIMIT.

SERVICE AREA

[EXTRACT FROM SERVICE AREA SECTION OF TECHNICAL STATEMENT ATTACHED TO THIS EXHIBIT 51.]

THE TABLE OF DISTANCES CIRCLE, OR THE ALTERNATIVE LARGEST STATION CIRCLE, IS DETERMINED BASED ON A RADIUS FROM THE REFERENCE POINT FOR THE STATION PROPOSING DTS OPERATION. THE DEFAULT REFERENCE POINT FOR A DTS OPERATION IS THE REFERENCE POINT ''ESTABLISHED IN THE FCC ORDER THAT CREATED OR MADE FINAL MODIFICATIONS TO THE POST-TRANSITION DTV TABLE OF ALLOTMENTS, SECTION 73.622(I), AND THE CORRESPONDING FACILITIES FOR THE STATIONS CHANNEL ASSIGNMENT AS SET FORTH IN THAT FCC ORDER.'' THE DEFAULT REFERENCE POINT FOR THE KNBC DTS NETWORK (34-13-32N, 118-3-52W) IS THE LOCATION OF THE SITE 1 TRANSMITTER AT MOUNT WILSON, WHICH IS THE REFERENCE POINT ESTABLISHED IN THE DTV TABLE OF ALLOTMENTS FOR KNBC.

AS CAN BE SEEN IN FIGURE 2, THE COMBINED COVERAGE CONTOUR OF THE PROPOSED DTS NETWORK (AS DEFINED IN SECTION 73.626(D)) IS WITHIN THE COMBINATION OF THE KNBC AUTHORIZED SERVICE AREA (WHICH MATCHES THE DTS SITE 1CONTOUR SHOWN IN ORANGE IN FIGURE 2) AND ITS LARGEST STATION CIRCLE (SHOWN IN BLACK IN FIGURE 2), WITH THE EXCEPTION OF ONE AREA TO THE NORTHEAST OF THE DTS SITE 2 TRANSMITTER WHERE ITS CONTOUR EXTENDS BEYOND THE LARGEST STATION CIRCLE BY A SIGNIFICANT AMOUNT AND A SMALL AREA TO THE NORTH-NORTHEAST OF THE DTS SITE 2 TRANSMITTER WHERE ITS CONTOUR EXTENDS BEYOND THE LARGEST STATION CIRCLE BY A MINUSCULE AMOUNT. THE EXTENSIONS RESULT FROM OPERATION WITH A COMMON ANTENNA THAT IS BEING OFFERED BY AMERICAN TOWER CORPORATION FOR USE BY ALL LOS ANGELES TELEVISION BROADCASTERS THAT CHOOSE TO OPERATE FROM THE TABLE MOUNTAIN SITE. THE ANTENNA HAS BEEN DESIGNED TO MEET THE CONSTRAINTS OF FITTING INTO THE SITE, PROVIDING CAPACITY FOR A LARGE NUMBER OF TELEVISION SERVICES MANY ON ADJACENT CHANNELS TO ONE ANOTHER AND ENABLING PROTECTION TO THE NEARBY JET PROPULSION LABORATORY SITE THAT IS BEHIND THE ANTENNA PATTERN. GIVEN ITS NATURE AS A COMMON FACILITY AND THE CONSTRAINTS OF THE SITE, THE ANTENNA CANNOT BE OPTIMIZED WITH RESPECT TO THE CONTOURS OF EACH OF THE STATIONS USING IT IN THEIR RESPECTIVE DTS NETWORK OPERATIONS, AND THERE IS INSUFFICIENT TOWER CAPACITY TO PERMIT EACH STATION TO HAVE ITS OWN ANTENNA.

THE CONTOUR EXTENSION TO THE NORTHEAST, WHILE SUBSTANTIAL IN AREA, IS IN A DESERT REGION WITH VERY LOW POPULATION. IT EXTENDS BEYOND THE LARGEST STATION CIRCLE BY 13.6 KM AT ITS WIDEST AND HAS AN AREA OF 948.6 SQUARE KM BUT A POPULATION OF ONLY 3,030, PER THE 2000 U.S. CENSUS. WHEN COMPARED TO THE POPULATION OF 818,490 WITHIN THE OVERALL DTS SITE 2 CONTOUR, THE POPULATION WITHIN THE EXTENSION AREA IS LESS THAN 0.4 PERCENT; WHEN COMPARED TO THE POPULATION OF 16,552,662 WITHIN THE ORIGINAL KNBC CONTOUR (NOW THE DTS SITE 1 CONTOUR), THE POPULATION WITHIN THE EXTENSION AREA IS LESS THAN 0.018 PERCENT. BY EITHER MEASURE THE POPULATION WITHIN THE EXTENSION IS DE MINIMIS. OF THE PEOPLE IN THE EXTENSION AREA, SOME 1,124 ARE PREDICTED TO RECEIVE NEW SERVICE FROM THE DTS SITE 2 TRANSMITTER. SIGNIFICANTLY, FOR ALL OF THESE PEOPLE, THE KNBC DTS SIGNALS WILL REPRESENT ONLY THE SECOND FULL-SERVICE TELEVISION SIGNALS THAT THEY ARE PREDICTED TO BE ABLE TO RECEIVE. THUS, THE EXTENSION WILL HELP TO PROVIDE ADDITIONAL SERVICE IN AN EXISTING GRAY AREA.

THE SMALLER CONTOUR EXTENSION TO THE NORTH-NORTHEAST ALSO IS LOCATED IN A DESERT REGION, CONTAINS AN AREA OF 4.778 SQUARE KM, AND HAS ZERO POPULATION; THUS, IT CAN BE CONSIDERED TO BE IMMATERIAL. TAKEN TOGETHER, THE CONTOUR EXTENSIONS SHOULD BE TREATED AS OF A MINIMAL AMOUNT, AS PROVIDED BY SECTION 73.626(F)(2), DUE TO THE DE MINIMIS NATURE OF THE POPULATION WITHIN THEM AND THE FACT THAT THE SMALL POPULATION THAT IS PREDICTED TO RECEIVE NEW SERVICE ACTUALLY IS A CURRENTLY-UNDERSERVED POPULATION IN A GRAY AREA. ACCORDINGLY, THE CONTOUR EXTENSIONS ARE PREDICTED TO PROVIDE A PUBLIC INTEREST BENEFIT. NEVERTHELESS, SHOULD THE COMMISSION DETERMINE THAT SUCH TREATMENT OF THE CONTOUR EXTENSIONS IS INAPPROPRIATE, THEN A WAIVER OF SECTION 73.626(F)(2) TO PERMIT USE OF THE COMMON ANTENNA AT THE DTS SITE 2 (TABLE MOUNTAIN) FACILITY IS RESPECTFULLY REQUESTED.

PRINCIPAL COMMUNITY COVERAGE

[EXTRACT FROM PRINCIPAL COMMUNITY COVERAGE SECTION OF TECHNICAL STATEMENT ATTACHED AT EXHIBIT 51 -- FOOTNOTE OMITTED.]

AS REQUIRED BY SECTION 73.625(A)(1) OF THE FCC RULES, THE TRANSMITTER LOCATION MUST BE CHOSEN SO AS TO PUT A MINIMUM F(50,90) FIELD STRENGTH OF 48 DBU OVER THE ENTIRE COMMUNITY TO BE SERVED. 73.625(A)(2) FURTHER REQUIRES THAT ''THE LOCATION OF THE ANTENNA MUST BE SO CHOSEN THAT THERE IS NOT A MAJOR OBSTRUCTION IN THE PATH OVER THE PRINCIPAL COMMUNITY TO BE SERVED.'' MOREOVER, SECTION 73.626(F)(4) REQUIRES THAT THE COVERAGE FROM ONE OR MORE DTS TRANSMITTERS BE SHOWN TO PROVIDE PRINCIPAL COMMUNITY COVERAGE AS REQUIRED BY SECTION 73.625(A). AS DEMONSTRATED BY THE 48 DBU CONTOUR OF THE MT WILSON TRANSMITTER (DTS SITE 1), SHOWN IN BLUE ON THE COVERAGE MAP OF FIGURE 2, THE TRANSMITTER LOCATION CHOSEN, COMBINED WITH THE OTHER CHARACTERISTICS OF THE TRANSMISSION SYSTEM, INDEED DOES DELIVER AT LEAST THE MINIMUM REQUIRED FIELD STRENGTH OVER THE ENTIRE COMMUNITY TO BE SERVED LOS ANGELES, CA. THE REQUIRED COVERAGE IS EVIDENT FROM THE FACT THAT THE DTS SITE 1 48 DBU CONTOUR ENCOMPASSES ALL OF THE COUNTY OF LOS ANGELES, SHOWN ON THE MAP IN FIGURE 2, IN WHICH THE CITY OF LOS ANGELES IS SITUATED. THUS, THE REQUIREMENTS OF 73.626(F)(4) ARE MET BY A SINGLE TRANSMITTER.

BECAUSE OF TERRAIN WITHIN THE CITY OF LOS ANGELES, HOWEVER, THERE REMAIN OBSTRUCTIONS IN THE PATHS OVER PORTIONS OF THE CITY. THOSE OBSTRUCTIONS ARE VARIOUS HILLS AND MOUNTAINS WITHIN LOS ANGELES AND WOULD IMPINGE UPON THE PROPAGATION PATHS TO ONE PART OF THE CITY OR ANOTHER OF SIGNALS FROM ANY TRANSMISSION SITE THAT MIGHT BE SELECTED. THE OBSTRUCTIONS WERE IN EXISTENCE AT THE TIME THE KNBC DIGITAL CONSTRUCTION PERMIT WAS GRANTED AND HAVE REMAINED IN EXISTENCE THROUGHOUT THE PERIOD OF KNBC OPERATION FROM MT WILSON.

ENVIRONMENTAL IMPACT / RADIO FREQUENCY RADIATION

[EXTRACT FROM ENVIRONMENTAL IMPACT / RADIO FREQUENCY RADIATION SECTION OF TECHNICAL STATEMENT ATTACHED AT EXHIBIT 51.]

NONE OF THE CONDITIONS SPECIFIED IN SECTION 1.1307 THAT WOULD REQUIRE THE PREPARATION OF AN ENVIRONMENTAL ASSESSMENT PERTAIN WITH RESPECT TO THE PROPOSED FACILITIES AT ANY OF THE SITES INCLUDED IN THIS APPLICATION. IN PARTICULAR, BECAUSE THEY WILL BE MOUNTED ON TOWERS AT EXISTING SITES, THE NEW OPERATIONS DO NOT IMPLICATE MANY OF THE CAUSES FOR FURTHER INVESTIGATION AND PREPARATION OF FURTHER REPORTS. ANY ENVIRONMENTAL ISSUES RESULTING FROM CONSTRUCTION OF NEW TOWERS OR CHANGES IN THE HEIGHTS OF THE TOWERS AT THE ADDED TRANSMITTERS (DTS SITES 2, 3, & 4) WILL BE ADDRESSED BY THE SITE DEVELOPERS.

WITH RESPECT TO RADIO FREQUENCY RADIATION EXPOSURE, OET BULLETIN NO. 65 PROVIDES METHODS FOR EVALUATING THE LEVEL OF EXPOSURE FOR BOTH EMPLOYEES (OCCUPATIONAL/CONTROLLED SITUATIONS) AND NON-EMPLOYEES (GENERAL POPULATION/UNCONTROLLED SITUATIONS). THE COMBINATIONS OF THE ANTENNA RADIATION PATTERNS, AS PROVIDED IN THE MANUFACTURER'S TECHNICAL SPECIFICATIONS, WITH THE ANTENNA HEIGHTS ABOVE GROUND LEVEL AND THE OPERATING POWER LEVELS INDICATE THAT THE POTENTIAL EXPOSURE WOULD BE LESS THAN THE MAXIMUM PERMISSIBLE EXPOSURE (MPE) LIMIT FOR GENERAL POPULATION / UNCONTROLLED SITUATIONS AT ALL THREE LOCATIONS (COUNTING DTS SITES 3 & 4 AS ONE). SPECIFICALLY, APPLICATION OF THE FORMULAS PROVIDED IN OET 65 YIELDS VALUES, IN PERCENT OF THE MPE LIMIT, OF 0.62 AT DTS SITE 1, 7.37 AT DTS SITE 2, AND 20.32 IN THE AGGREGATE AT DTS SITES 3 & 4. IT SHOULD BE NOTED THAT THESE EVALUATIONS ASSUME FLAT TERRAIN AROUND THE VARIOUS SITES. CONSEQUENTLY, FURTHER ANALYSIS, USING DETAILS OF THE TERRAIN SURROUNDING THE SITES, MAY RESULT IN A FINDING OF LOWER PREDICTED RADIATION VALUES THAN REPORTED HEREIN. AS A RESULT OF THE LOW PERCENTAGE OF MPE, THE DTS SITE 1 OPERATIONS ARE CATEGORICALLY EXCLUDED FROM THE NECESSITY TO CONDUCT DETAILED RF EXPOSURE ANALYSIS OF THE SITE. FOR DTS SITES 2, 3, & 4, MEASUREMENTS WILL BE CONDUCTED TO CONFIRM THAT THEY DO NOT CONTRIBUTE TO RADIO FREQUENCY RADIATION, FROM ALL SOURCES, IN ACCESSIBLE AREAS, THAT EXCEEDS THE APPROPRIATE MPE LIMITS.

NOTWITHSTANDING THE FOREGOING, NBC RECOGNIZES ITS RESPONSIBILITY FOR THE SAFETY AND HEALTH OF EMPLOYEES AND CONTRACTORS WHEN EXPOSED TO RF RADIATION CONDITIONS. IT WILL TAKE THE STEPS NECESSARY TO ASSURE THAT PERSONNEL WORKING AT EACH FACILITY AND ON THEIR TOWERS AND ANTENNAS ARE PROTECTED FROM EXPOSURE TO RF RADIATION LEVELS EXCEEDING THOSE SPECIFIED IN THE COMMISSIONS RULES. IT WILL TAKE SUCH STEPS IN COORDINATION WITH OTHER SITE USERS AT SITES THAT ARE SHARED. THE STEPS TO BE TAKEN WILL INCLUDE MEASUREMENTS AND MONITORING AS WELL AS POWER REDUCTIONS OR TURNING OFF THE TRANSMITTERS, IF NECESSARY TO ENSURE A SAFE WORKING ENVIRONMENT.

FACILITIES -- RELEVANT TO DTS SITE 1

[EXTRACT OF FACILITIES SECTION + CHARTS & TABLES RELEVANT TO DTS SITE 1 FROM TECHNICAL STATEMENT ATTACHED TO EXHIBIT 51.]

THE FACILITIES REQUESTED IN THIS APPLICATION INCLUDE CONTINUED OPERATION AT 665 KW ERP AT A HEIGHT ABOVE AVERAGE TERRAIN OF 991 METERS AT THE MT WILSON SITE, OPERATION AT 50 KW ERP AT 696.5 METERS HAAT AT TABLE MOUNTAIN, AND OPERATION AT 25.1 KW AT 588.5 METERS HAAT AND AT 16.74 KW AT 568.5 METERS HAAT AT OAT MOUNTAIN. THE CURRENTLY AUTHORIZED FACILITY AT THE MT WILSON SITE MEETS THE REQUIREMENTS OF SECTION 73.622(F)(5), AS ITS COMBINATION OF POWER AND ANTENNA HEIGHT DOES NOT PRODUCE A PREDICTED NOISE-LIMITED CONTOUR THE AREA OF WHICH EXCEEDS THAT OF THE LARGEST SUCH AREA PRODUCED BY ANOTHER STATION IN THE SAME MARKET. THE RELATIONSHIPS BETWEEN THE PARAMETERS IN THE CASES OF THE GAP-FILLER TRANSMITTERS RESULT IN POWER/HEIGHT COMBINATIONS THAT MEET THE REQUIREMENTS FOR MAXIMUM ALLOWABLE FACILITIES SPECIFIED BY THE TABLE IN SECTION 73.622(F)(8)(I) OF THE COMMISSIONS RULES. THE BASIC CHARACTERISTICS OF EACH OF THE TRANSMITTERS PROPOSED IN THE KNBC DTS NETWORK ARE GIVEN IN FIGURES 1A, 1B, 1C, AND 1D AT THE END OF THIS TECHNICAL STATEMENT AND IN THE RELATED DTS ENGINEERING PORTIONS OF THE FORM 301 APPLICATION ONE FOR EACH TRANSMITTER.

THREE FUNDAMENTAL ANTENNA DESIGNS ARE PROPOSED FOR USE IN THE KNBC DTS NETWORK. THE MT WILSON (DTS SITE 1) ANTENNA IS A RELATIVELY CONVENTIONAL, OMNIDIRECTIONAL, CENTER-FED, SLOTTED COAXIAL DESIGN. IT HAS ONE DEGREE OF ELECTRICAL BEAM TILT AND IS INSTALLED WITH ONE DEGREE OF MECHANICAL BEAM TILT DOWNWARD TOWARD 215 DEGREES. IT HAS BEEN IN SERVICE FOR KNBC SINCE THE STATION FIRST INITIATED DIGITAL TRANSMISSION IN 1998.

THE ANTENNA DESIGN AT THE TABLE MOUNTAIN SITE (DTS SITE 2) WILL BE A PANEL ARRAY, USING BROADBAND PANELS AND A CORPORATE FEED. IT WILL CONSIST OF A TOTAL OF SIXTEEN PANELS IN TWO COLUMNS OF EIGHT EACH AND WILL HAVE THREE MAIN LOBES IN ITS AZIMUTH PATTERN. A SIGNIFICANT AMOUNT OF ELECTRICAL BEAM TILT WILL BE USED, WITH A SUBSTANTIAL NOTCH IN THE RADIATION ABOVE THE MAIN BEAM. THE COMBINATION OF THE ELECTRICAL BEAM TILT AND THE NOTCH WILL PERMIT THE APPLICATION OF MECHANICAL BEAM TILT TO THE ANTENNA IN SUCH A WAY THAT THE FORWARD LOBES WILL BE ORIENTED TO A RELATIVELY CONVENTIONAL DEPRESSION ANGLE (0.7 DEGREES), WHILE THE BACK LOBES WILL BE DRIVEN INTO THE GROUND, WITH THE NOTCH OCCURRING AT A DEPRESSION ANGLE THAT WILL PERMIT SUBSTANTIAL REDUCTION IN POWER TOWARD A NEARBY SCIENTIFIC INSTALLATION. THIS COMBINATION OF FACTORS IS DISCUSSED IN MORE DETAIL BELOW.

THE ANTENNA DESIGNS AT THE OAT MOUNTAIN SITE WILL BE RELATIVELY SIMPLE, SINGLE-COLUMN ARRAYS OF SIX PANELS AND FOUR PANELS EACH FOR DTS SITES 3 AND 4, RESPECTIVELY. EACH WILL HAVE A SINGLE MAIN LOBE IN ITS AZIMUTH PATTERN. NO ELECTRICAL BEAM TILT WILL BE USED, WITH ONLY MECHANICAL BEAM TILT APPLIED TO CONTROL THE EXTENT OF SIGNAL PROJECTION FROM THE ANTENNAS.

A PLOT OF THE PROPOSED PNLCS OF THE FOUR TRANSMITTERS IS PROVIDED IN FIGURE 2, WHERE THE EXISTING SITE 1 CONTOUR IS IN ORANGE, THE PROPOSED SITE 2 CONTOUR IS IN OLIVE, THE PROPOSED SITE 3 CONTOUR IS IN GREEN, AND THE PROPOSED SITE 4 CONTOUR IS IN VIOLET. IN ITS CURRENT CONFIGURATION, THE MAIN, MT WILSON TRANSMITTER FACILITY AUTHORIZED BY THE EXISTING CONSTRUCTION PERMIT (HEREIN, DTS SITE 1) ALREADY COVERS THE ENTIRE AUTHORIZED SERVICE AREA OF THE STATION; THUS, THE REQUIREMENTS OF SECTION 73.626(F)(1) WOULD BE MET BY THAT FACILITY ALONE. BY VIRTUE OF THE OVERLAP OF THE CONTOURS OF THE TRANSMITTERS, THEY ARE CONTIGUOUS, THEREBY MEETING THE REQUIREMENTS OF SECTION 73.626(F)(3). ALSO SHOWN IN FIGURE 2, IN BLUE, IS THE 48 DBU CONTOUR OF THE DTS SITE 1 FACILITY, WHICH CAN BE SEEN TO ENCOMPASS THE ENTIRE COUNTY OF LOS ANGELES, CA, IN WHICH IS LOCATED THE CITY OF LOS ANGELES, TO WHICH KNBC IS LICENSED. ALL FOUR TRANSMITTERS IN THE PROPOSED DTS NETWORK ARE LOCATED WITHIN THE KNBC ''LARGEST STATION ALTERNATIVE'' TO THE TABLE OF DISTANCES AREA (DISCUSSED IN DETAIL BELOW), CONSEQUENTLY MEETING THE REQUIREMENTS OF SECTION 73.626(F)(6).

THE CHARACTERISTICS OF THE DTS SITE 1 (MT WILSON) FACILITY ARE FULLY DESCRIBED IN FIGURE 1A. THE ANTENNA IS INSTALLED WITH 1 DEGREE OF MECHANICAL BEAM TILT DOWNWARD IN THE DIRECTION OF 215 DEGREES TRUE. THE ANTENNA HAS ELLIPTICAL POLARIZATION, WITH 16.67 PERCENT OF THE POWER APPLIED TO THE VERTICAL POLARIZATION COMPONENT. ELEVATION POWER GAIN OF THE ANTENNA IS 13.80 (11.38 DBD) IN THE HORIZONTAL POLARIZATION COMPONENT AND 2.80 (4.39 DBD) IN THE VERTICAL POLARIZATION COMPONENT AT THE VERTICAL BEAM MAXIMUM (1.0 DEGREE BELOW THE PLANE ORTHOGONAL TO THE AXIS OF THE ANTENNA AND THROUGH ITS RADIATION CENTER). AZIMUTH POWER GAIN OF THE ANTENNA IN THE HORIZONTAL POLARIZATION COMPONENT IS VIRTUALLY NIL (1.023 OR 0.10 DBD). THE MECHANICAL BEAM TILT CAUSES THE GAIN OF THE HORIZONTAL POLARIZATION COMPONENT TO VARY IN THE HORIZONTAL PLANE BETWEEN 13.80 (11.38 DBD) AT 35 DEGREES AZIMUTH AND 8.79 (9.44 DBD) AT 215 DEGREES AZIMUTH.

A PLOT OF THE AZIMUTHAL RADIATION PATTERN OF THE DTS SITE 1 ANTENNA IN RELATIVE FIELD VALUES OF THE HORIZONTAL POLARIZATION COMPONENT, PRIOR TO THE APPLICATION OF MECHANICAL BEAM TILT, (I.E., 1 DEGREE BELOW THE PLANE ORTHOGONAL TO THE AXIS OF THE ANTENNA AND THROUGH ITS RADIATION CENTER) IS INCLUDED AS FIGURE 3. THE AZIMUTHAL RADIATION PATTERN IN RELATIVE FIELD VALUES OF THE HORIZONTAL POLARIZATION COMPONENT IN THE HORIZONTAL PLANE, AFTER APPLICATION OF MECHANICAL BEAM TILT, IS INCLUDED AS FIGURE 4.   THE AZIMUTHAL POWER PATTERN OF THE HORIZONTAL POLARIZATION COMPONENT, EXPRESSED IN DECIBELS RELATIVE TO 1 KW (DBK), PRIOR TO THE APPLICATION OF MECHANICAL BEAM TILT, (I.E., 1 DEGREE BELOW THE PLANE ORTHOGONAL TO THE AXIS OF THE ANTENNA AND THROUGH ITS RADIATION CENTER) IS INCLUDED AS FIGURE 5. THE AZIMUTHAL POWER PATTERN OF THE HORIZONTAL POLARIZATION COMPONENT, EXPRESSED IN DECIBELS RELATIVE TO 1 KW (DBK) IN THE HORIZONTAL PLANE, IS PLOTTED IN FIGURE 6. TABULATED AZIMUTHAL FIELD AND POWER VALUES OF THE HORIZONTAL POLARIZATION COMPONENT DERIVED FROM THE DATA ARRAYS USED TO GENERATE FIGURES 3 THROUGH 6 ARE GIVEN IN FIGURE 7. THE ELEVATION RADIATION PATTERN IN RELATIVE FIELD VALUES OF THE HORIZONTAL POLARIZATION COMPONENT ALONG THE AXIS OF THE ANTENNA IS INCLUDED AS FIGURE 8. THE ELEVATION POWER PATTERN OF THE HORIZONTAL POLARIZATION COMPONENT, EXPRESSED IN DECIBELS RELATIVE TO 1 KW (DBK) ALONG THE AXIS OF THE ANTENNA, IS PLOTTED IN FIGURE 9. TABULATED ELEVATION FIELD AND POWER VALUES OF THE HORIZONTAL POLARIZATION COMPONENT DERIVED FROM THE DATA ARRAYS USED TO GENERATE FIGURES 8 & 9 ARE GIVEN IN FIGURE 10.

BECAUSE OF THE MECHANICAL BEAM TILT APPLIED TO THE SITE 1 ANTENNA, ITS ELEVATION PATTERN VARIES WITH AZIMUTH, AND ITS AZIMUTH PATTERN VARIES WITH DEPRESSION ANGLE. THEREFORE, COMPLETE PATTERN DATA FOR THE ANTENNA FOR DTS SITE 1 IS BEING SUPPLIED THROUGH A COMPLEX ELEVATION PATTERN DATA FILE UPLOADED TO THE CDBS ELECTRONIC FILING SYSTEM. IN THAT FILE, DEPRESSION ANGLE VALUES ARE INCLUDED IN THE FIRST COLUMN, AND AZIMUTH VALUES ARE INCLUDED IN THE FIRST ROW. THE AZIMUTH AND ELEVATION PATTERN PLOTS AND TABULAR DATA SUPPLIED IN THIS TECHNICAL STATEMENT ARE FOR REFERENCE ONLY AND ARE INTENDED TO HELP IN VISUALIZATION OF THE CHARACTERISTICS OF THE ANTENNA. FULL SPECIFICATION OF THE ANTENNA PATTERN IS CONTAINED WHOLLY AND ONLY WITHIN THE ELEVATION PATTERN DATA FILE UPLOADED WITH THE FORM 301 APPLICATION.

IT SHOULD BE NOTED THAT, DUE TO LIMITATIONS IN THE FORM 301 DTS ENGINEERING PAGES IN THE CDBS ELECTRONIC FILING SYSTEM (EFS) AND BECAUSE THE VALUES IN THE AZIMUTH PATTERN RELATIVE FIELD DATA INPUT THERE ARE MULTIPLIED BY THE DATA IN THE ELEVATION PATTERN DATA FILE IN THE COMMISSIONS PROCESSING SOFTWARE, IT IS NOT POSSIBLE TO ENTER DATA INTO THE AZIMUTH PATTERN INPUT FIELDS THAT ARE REPRESENTATIVE OF THE HORIZONTAL PLANE PATTERN SUBSEQUENT TO INCLUSION OF THE EFFECTS OF MECHANICAL BEAM TILT. DOING SO WOULD RESULT IN DISTORTION OF THE ACTUAL PATTERN DATA AND LEAD TO INCORRECT ANALYSES OF THE PREDICTED INTERFERENCE FROM OR TO A STATION UNDER STUDY. MOREOVER, SINCE THE COMMISSIONS PROCESSING SOFTWARE DOES NOT HAVE THE ABILITY TO APPLY MECHANICAL BEAM TILT TO MORE THAN ONE ANTENNA IN A STUDY AND DOES NOT CURRENTLY APPLY MECHANICAL TILT IN A NON-DISTORTING WAY TO AN ANTENNA PATTERN, IT IS NECESSARY TO PUT DATA REPRESENTING THE RADIATION PATTERN OF EACH ANTENNA SUBSEQUENT TO APPLICATION OF MECHANICAL TILT INTO THE CORRESPONDING UPLOADED ELEVATION PATTERN DATA FILE, WHICH IS THE ONLY AVAILABLE MECHANISM THAT HAS SUFFICIENT DATA REPRESENTATION CAPACITY TO CARRY THE REQUIRED AMOUNT OF DATA. AS A RESULT OF ALL OF THIS, IT IS NECESSARY EITHER TO SET THE CHECK BOX RELATED TO THE AZIMUTH PATTERN INPUT FIELDS TO ''N/A'', WHICH PARENTHETICALLY ALSO INDICATES ''NON-DIRECTIONAL'', OR NOT TO CHECK THE ''N/A'' BOX BUT TO PUT VALUES OF 1.000 IN ALL OF THE AZIMUTH PATTERN DATA FIELDS. THE LATTER APPROACH AT LEAST INDICATES THAT THE ANTENNA IS DIRECTIONAL AND THEREFORE WAS TAKEN IN THE INSTANT APPLICATION FOR EACH OF THE DTS SITES AND THEIR ANTENNA PATTERNS.

THE PROPOSED DTS SITE 2 (TABLE MOUNTAIN) ANTENNA WILL HAVE COLUMNS OF PANELS FACING 62 AND 327 DEGREES TRUE, WITH RESULTING MAJOR AZIMUTH LOBES AT 15, 61, AND 328 DEGREES TRUE. IT WILL HAVE AN ELEVATION PATTERN WITH ITS MAIN LOBE 3 DEGREES BELOW THE PLANE ORTHOGONAL TO THE AXIS OF THE ANTENNA AND THROUGH ITS RADIATION CENTER. THE ELEVATION PATTERN ALSO WILL CONTAIN A NOTCH ABOVE THE MAIN LOBE AT 0.2 DEGREE ABOVE THE PLANE ORTHOGONAL TO THE AXIS OF THE ANTENNA AND THROUGH ITS RADIATION CENTER. MECHANICAL BEAM TILT OF 2.3 DEGREES DOWNWARD WILL BE APPLIED TO THE ANTENNA AT A BEARING OF 204 DEGREES TRUE. THIS WILL RESULT IN THE MAIN BEAM BEING LIFTED TO A DEPRESSION ANGLE OF 0.7 DEGREES TOWARD A BEARING OF 24 DEGREES TRUE AND BEING PUSHED DOWN TO A DEPRESSION ANGLE OF 5.3 DEGREES AT THE 204-DEGREE BEARING. IT ALSO WILL RESULT IN THE NOTCH ABOVE THE MAIN BEAM BEING PUSHED DOWN TO A DEPRESSION ANGLE OF 2.1 DEGREES AT THE 204-DEGREE BEARING.

THE CHARACTERISTICS AND PARAMETERS OF DTS SITE 2 ARE FULLY DESCRIBED IN FIGURE 1B. THE DTS SITE 2 ANTENNA WILL HAVE CIRCULAR POLARIZATION, WITH EQUAL POWER APPLIED TO BOTH THE HORIZONTAL AND VERTICAL POLARIZATION COMPONENTS; THUS THE EFFECTIVE RADIATED POWER OF EACH INDIVIDUAL COMPONENT IS BASED ON HALF THE POWER INPUT TO THE ANTENNA. ELEVATION POWER GAIN OF THE ANTENNA DESIGN FOR DTS SITE 2, AT THE AZIMUTH OF BEAM MAXIMUM (61 DEGREES) AND IN EACH OF THE HORIZONTAL AND VERTICAL POLARIZATION COMPONENTS, IS 12.90 (11.12 DBD) AT THE BEAM MAXIMUM (3.0 DEGREES BELOW THE PLANE ORTHOGONAL TO THE AXIS OF THE ANTENNA AND THROUGH ITS RADIATION CENTER) AND JUST OVER 0.0029 (25.36 DBD) AT THE NULL ABOVE THE MAIN BEAM (0.2 DEGREES ABOVE THE PLANE ORTHOGONAL TO THE AXIS OF THE ANTENNA AND THROUGH ITS RADIATION CENTER). THE AZIMUTH POWER GAIN, AT THE DEPRESSION ANGLE OF BEAM MAXIMUM (3.0 DEGREES BELOW THE PLANE ORTHOGONAL TO THE AXIS OF THE ANTENNA AND THROUGH ITS RADIATION CENTER) AND IN EACH OF THE HORIZONTAL AND VERTICAL POLARIZATION COMPONENTS IS 2.90 (4.62 DB). THE TOTAL POWER GAIN IN EACH OF THE HORIZONTAL AND VERTICAL POLARIZATION COMPONENTS IN THE MAIN BEAM IS 37.41 (15.73 DBD). THE MECHANICAL BEAM TILT CAUSES THE GAIN OF EACH OF THE HORIZONTAL AND VERTICAL POLARIZATION COMPONENTS TO VARY IN THE HORIZONTAL PLANE BETWEEN 23.61 (13.73 DBD) AT 53 DEGREES AZIMUTH AND 0.000002647 ( 55.77 DBD) AT 194 DEGREES AZIMUTH.

A PLOT OF THE DTS SITE 2 ANTENNA AZIMUTHAL RADIATION PATTERN IN RELATIVE FIELD VALUES, AT THE DEPRESSION ANGLE HAVING MAXIMUM FIELD (3.0 DEGREES BELOW THE PLANE ORTHOGONAL TO THE AXIS OF THE ANTENNA AND THROUGH ITS RADIATION CENTER), IS INCLUDED AS FIGURE 11. THE AZIMUTHAL POWER PATTERN EXPRESSED IN DECIBELS RELATIVE TO 1 KW (DBK), AT THE DEPRESSION ANGLE HAVING MAXIMUM POWER (ALSO 3.0 DEGREES BELOW THE PLANE ORTHOGONAL TO THE AXIS OF THE ANTENNA AND THROUGH ITS RADIATION CENTER), IS PLOTTED IN FIGURE 12. THE TABULATED AZIMUTHAL FIELD AND POWER VALUES ARE GIVEN IN FIGURE 13. THE ELEVATION RADIATION PATTERN IN RELATIVE FIELD VALUES ALONG THE AXIS OF THE ANTENNA, IN THE AZIMUTHAL DIRECTION HAVING MAXIMUM FIELD (61 DEGREES), IS INCLUDED AS FIGURE 14. THE ELEVATION POWER PATTERN EXPRESSED IN DECIBELS RELATIVE TO 1 KW (DBK) ALONG THE AXIS OF THE ANTENNA, IN THE AZIMUTHAL DIRECTION HAVING MAXIMUM POWER (ALSO 61 DEGREES), IS PLOTTED IN FIGURE 15. THE TABULATED ELEVATION FIELD AND POWER VALUES ARE GIVEN IN FIGURE 16.

BECAUSE OF THE MECHANICAL BEAM TILT APPLIED TO THE DTS SITE 2 ANTENNA, ITS ELEVATION PATTERN VARIES WITH AZIMUTH, AND ITS AZIMUTH PATTERN VARIES WITH DEPRESSION ANGLE. THEREFORE, COMPLETE PATTERN DATA FOR THE ANTENNA FOR DTS SITE 2 ARE BEING SUPPLIED THROUGH A COMPLEX ELEVATION PATTERN DATA FILE UPLOADED TO THE CDBS ELECTRONIC FILING SYSTEM. IN THAT FILE, DEPRESSION ANGLE VALUES ARE INCLUDED IN THE FIRST COLUMN, AND AZIMUTH VALUES ARE INCLUDED IN THE FIRST ROW. THE AZIMUTH AND ELEVATION PATTERN PLOTS AND TABULAR DATA SUPPLIED IN THIS TECHNICAL STATEMENT ARE FOR REFERENCE ONLY AND ARE INTENDED TO HELP IN VISUALIZATION OF THE CHARACTERISTICS OF THE ANTENNA. FULL SPECIFICATION OF THE ANTENNA PATTERN IS CONTAINED WHOLLY AND ONLY WITHIN THE ELEVATION PATTERN DATA FILE UPLOADED WITH THE FORM 301 APPLICATION. IT SHOULD BE NOTED THAT THE LIMITATIONS OF THE CDBS EFS FORM 301 DTS ENGINEERING WEB PAGE REGARDING INCLUSION OF AZIMUTH PATTERN RELATIVE FIELD VALUES AND THE RELATED CHECK BOX, DESCRIBED ABOVE WITH RESPECT TO THE DTS SITE 1 ANTENNA, APPLY EQUALLY WITH RESPECT TO THE DTS SITE 2 ANTENNA AND THAT THE SAME APPROACH TAKEN FOR SITE 1 HAS BEEN FOLLOWED FOR SITE 2.

THE PROPOSED DTS SITES 3 AND 4 ANTENNAS (BOTH OF WHICH WILL BE AT OAT MOUNTAIN) WILL BE COMPOSED OF SINGLE COLUMNS OF PANELS 6 FOR DTS SITE 3 AND 4 FOR DTS SITE 4. THERE WILL BE NO ELECTRICAL BEAM TILT APPLIED TO THE ELEVATION PATTERN OF EITHER ANTENNA; ONLY MECHANICAL BEAM TILT WILL BE APPLIED TO EACH OF THEM. THE DTS SITE 3 ANTENNA WILL BE ORIENTED WITH ITS MAIN BEAM TOWARD AN AZIMUTH OF 255 DEGREES TRUE AND 1.5 DEGREES BELOW THE HORIZONTAL AT THE SAME HEADING. THE DTS SITE 4 ANTENNA WILL BE MOUNTED 20 METERS BELOW THE DTS SITE 3 ANTENNA ON THE SAME TOWER. IT WILL BE ORIENTED WITH ITS MAIN BEAM TOWARD AN AZIMUTH OF 15 DEGREES AND 2.0 DEGREES BELOW THE HORIZONTAL AT THE SAME HEADING.

THE CHARACTERISTICS AND PARAMETERS OF DTS SITES 3 AND 4 ARE FULLY DESCRIBED IN FIGURES 1C AND 1D, RESPECTIVELY. THEIR ANTENNAS WILL HAVE CIRCULAR POLARIZATION, WITH EQUAL POWER APPLIED TO BOTH THE HORIZONTAL AND VERTICAL POLARIZATION COMPONENTS; THUS, THE EFFECTIVE RADIATED POWER OF EACH INDIVIDUAL COMPONENT IS BASED ON HALF THE POWER INPUT TO ITS RESPECTIVE ANTENNA. ELEVATION POWER GAIN OF THE ANTENNA DESIGN FOR DTS SITE 3, AT THE AZIMUTH OF BEAM MAXIMUM (255 DEGREES) AND IN EACH OF THE HORIZONTAL AND VERTICAL POLARIZATION COMPONENTS, IS 14.24 (11.54 DBD) AT THE BEAM MAXIMUM (IN THE PLANE ORTHOGONAL TO THE AXIS OF THE ANTENNA AND THROUGH ITS RADIATION CENTER). THE AZIMUTH POWER GAIN, AT THE DEPRESSION ANGLE OF BEAM MAXIMUM (IN THE PLANE ORTHOGONAL TO THE AXIS OF THE ANTENNA AND THROUGH ITS RADIATION CENTER) AND IN EACH OF THE HORIZONTAL AND VERTICAL POLARIZATION COMPONENTS IS 5.63 (7.51 DB). THE TOTAL POWER GAIN IN EACH OF THE HORIZONTAL AND VERTICAL POLARIZATION COMPONENTS IN THE MAIN BEAM IS 80.17 (19.04 DBD). THE MECHANICAL BEAM TILT CAUSES THE GAIN OF EACH OF THE HORIZONTAL AND VERTICAL POLARIZATION COMPONENTS TO VARY IN THE HORIZONTAL PLANE BETWEEN 53.80 (17.31 DBD) AT 255 DEGREES AZIMUTH AND 0.27878 ( 5.55 DBD) AT BOTH 43 AND 107 DEGREES AZIMUTH.

ELEVATION POWER GAIN OF THE ANTENNA DESIGN FOR DTS SITE 4, AT THE AZIMUTH OF BEAM MAXIMUM (15 DEGREES) AND IN EACH OF THE HORIZONTAL AND VERTICAL POLARIZATION COMPONENTS, IS 9.50 (9.78 DBD) AT THE BEAM MAXIMUM (IN THE PLANE ORTHOGONAL TO THE AXIS OF THE ANTENNA AND THROUGH ITS RADIATION CENTER). THE AZIMUTH POWER GAIN, AT THE DEPRESSION ANGLE OF BEAM MAXIMUM (IN THE PLANE ORTHOGONAL TO THE AXIS OF THE ANTENNA AND THROUGH ITS RADIATION CENTER) AND IN EACH OF THE HORIZONTAL AND VERTICAL POLARIZATION COMPONENTS IS 5.63 (7.51 DB). THE TOTAL POWER GAIN IN EACH OF THE HORIZONTAL AND VERTICAL POLARIZATION COMPONENTS IN THE MAIN BEAM IS 53.49 (17.28 DBD). THE MECHANICAL BEAM TILT CAUSES THE GAIN OF EACH OF THE HORIZONTAL AND VERTICAL POLARIZATION COMPONENTS TO VARY IN THE HORIZONTAL PLANE BETWEEN 38.83 (15.89 DBD) AT 15 DEGREES AZIMUTH AND 0.1965 ( 7.07 DBD) AT BOTH 163 AND 227 DEGREES AZIMUTH.

PLOTS OF THE AZIMUTHAL RADIATION PATTERNS OF THE DTS SITES 3 & 4 ANTENNAS IN RELATIVE FIELD VALUES, AT THE DEPRESSION ANGLES HAVING MAXIMUM FIELD (IN THE PLANES ORTHOGONAL TO THE AXES OF THE ANTENNAS AND THROUGH THEIR RADIATION CENTERS), ARE INCLUDED AS FIGURES 17A AND 17B.

THE TABULATED ELEVATION FIELD AND POWER VALUES ARE GIVEN IN FIGURE 22.

BECAUSE OF THE MECHANICAL BEAM TILT APPLIED TO THE DTS SITES 3 & 4 ANTENNAS, THEIR ELEVATION PATTERNS VARY WITH AZIMUTH, AND THEIR AZIMUTH PATTERNS VARY WITH DEPRESSION ANGLE.

FACILITIES -- RELEVANT TO DTS SITE 2

[EXTRACT OF FACILITIES SECTION + CHARTS & TABLES RELEVANT TO DTS SITE 2 FROM TECHNICAL STATEMENT ATTACHED TO EXHIBIT 51.]

THE FACILITIES REQUESTED IN THIS APPLICATION INCLUDE CONTINUED OPERATION AT 665 KW ERP AT A HEIGHT ABOVE AVERAGE TERRAIN OF 991 METERS AT THE MT WILSON SITE, OPERATION AT 50 KW ERP AT 696.5 METERS HAAT AT TABLE MOUNTAIN, AND OPERATION AT 25.1 KW AT 588.5 METERS HAAT AND AT 16.74 KW AT 568.5 METERS HAAT AT OAT MOUNTAIN. THE CURRENTLY AUTHORIZED FACILITY AT THE MT WILSON SITE MEETS THE REQUIREMENTS OF SECTION 73.622(F)(5), AS ITS COMBINATION OF POWER AND ANTENNA HEIGHT DOES NOT PRODUCE A PREDICTED NOISE-LIMITED CONTOUR THE AREA OF WHICH EXCEEDS THAT OF THE LARGEST SUCH AREA PRODUCED BY ANOTHER STATION IN THE SAME MARKET. THE RELATIONSHIPS BETWEEN THE PARAMETERS IN THE CASES OF THE GAP-FILLER TRANSMITTERS RESULT IN POWER/HEIGHT COMBINATIONS THAT MEET THE REQUIREMENTS FOR MAXIMUM ALLOWABLE FACILITIES SPECIFIED BY THE TABLE IN 73.622(F)(8)(I) OF THE COMMISSIONS RULES. THE BASIC CHARACTERISTICS OF EACH OF THE TRANSMITTERS PROPOSED IN THE KNBC DTS NETWORK ARE GIVEN IN FIGURES 1A, 1B, 1C, AND 1D AT THE END OF THIS TECHNICAL STATEMENT AND IN THE RELATED DTS ENGINEERING PORTIONS OF THE FORM 301 APPLICATION ONE FOR EACH TRANSMITTER.

THREE FUNDAMENTAL ANTENNA DESIGNS ARE PROPOSED FOR USE IN THE KNBC DTS NETWORK. THE MT WILSON (DTS SITE 1) ANTENNA IS A RELATIVELY CONVENTIONAL, OMNIDIRECTIONAL, CENTER-FED, SLOTTED COAXIAL DESIGN. IT HAS ONE DEGREE OF ELECTRICAL BEAM TILT AND IS INSTALLED WITH ONE DEGREE OF MECHANICAL BEAM TILT DOWNWARD TOWARD 215 DEGREES. IT HAS BEEN IN SERVICE FOR KNBC SINCE THE STATION FIRST INITIATED DIGITAL TRANSMISSION IN 1998.

THE ANTENNA DESIGN AT THE TABLE MOUNTAIN SITE (DTS SITE 2) WILL BE A PANEL ARRAY, USING BROADBAND PANELS AND A CORPORATE FEED. IT WILL CONSIST OF A TOTAL OF SIXTEEN PANELS IN TWO COLUMNS OF EIGHT EACH AND WILL HAVE THREE MAIN LOBES IN ITS AZIMUTH PATTERN. A SIGNIFICANT AMOUNT OF ELECTRICAL BEAM TILT WILL BE USED, WITH A SUBSTANTIAL NOTCH IN THE RADIATION ABOVE THE MAIN BEAM. THE COMBINATION OF THE ELECTRICAL BEAM TILT AND THE NOTCH WILL PERMIT THE APPLICATION OF MECHANICAL BEAM TILT TO THE ANTENNA IN SUCH A WAY THAT THE FORWARD LOBES WILL BE ORIENTED TO A RELATIVELY CONVENTIONAL DEPRESSION ANGLE (0.7 DEGREES), WHILE THE BACK LOBES WILL BE DRIVEN INTO THE GROUND, WITH THE NOTCH OCCURRING AT A DEPRESSION ANGLE THAT WILL PERMIT SUBSTANTIAL REDUCTION IN POWER TOWARD A NEARBY SCIENTIFIC INSTALLATION. THIS COMBINATION OF FACTORS IS DISCUSSED IN MORE DETAIL BELOW.

THE ANTENNA DESIGNS AT THE OAT MOUNTAIN SITE WILL BE RELATIVELY SIMPLE, SINGLE-COLUMN ARRAYS OF SIX PANELS AND FOUR PANELS EACH FOR DTS SITES 3 AND 4, RESPECTIVELY. EACH WILL HAVE A SINGLE MAIN LOBE IN ITS AZIMUTH PATTERN. NO ELECTRICAL BEAM TILT WILL BE USED, WITH ONLY MECHANICAL BEAM TILT APPLIED TO CONTROL THE EXTENT OF SIGNAL PROJECTION FROM THE ANTENNAS.

A PLOT OF THE PROPOSED PNLCS OF THE FOUR TRANSMITTERS IS PROVIDED IN FIGURE 2, WHERE THE EXISTING SITE 1 CONTOUR IS IN ORANGE, THE PROPOSED SITE 2 CONTOUR IS IN OLIVE, THE PROPOSED SITE 3 CONTOUR IS IN GREEN, AND THE PROPOSED SITE 4 CONTOUR IS IN VIOLET. IN ITS CURRENT CONFIGURATION, THE MAIN, MT WILSON TRANSMITTER FACILITY AUTHORIZED BY THE EXISTING CONSTRUCTION PERMIT (HEREIN, DTS SITE 1) ALREADY COVERS THE ENTIRE AUTHORIZED SERVICE AREA OF THE STATION; THUS, THE REQUIREMENTS OF SECTION 73.626(F)(1) WOULD BE MET BY THAT FACILITY ALONE. BY VIRTUE OF THE OVERLAP OF THE CONTOURS OF THE TRANSMITTERS, THEY ARE CONTIGUOUS, THEREBY MEETING THE REQUIREMENTS OF 73.626(F)(3). ALSO SHOWN IN FIGURE 2, IN BLUE, IS THE 48 DBU CONTOUR OF THE DTS SITE 1 FACILITY, WHICH CAN BE SEEN TO ENCOMPASS THE ENTIRE COUNTY OF LOS ANGELES, CA, IN WHICH IS LOCATED THE CITY OF LOS ANGELES, TO WHICH KNBC IS LICENSED. ALL FOUR TRANSMITTERS IN THE PROPOSED DTS NETWORK ARE LOCATED WITHIN THE KNBC ''LARGEST STATION'' ALTERNATIVE TO THE TABLE OF DISTANCES AREA (DISCUSSED IN DETAIL BELOW), CONSEQUENTLY MEETING THE REQUIREMENTS OF SECTION 73.626(F)(6).

THE CHARACTERISTICS OF THE DTS SITE 1 (MT WILSON) FACILITY ARE FULLY DESCRIBED IN FIGURE 1A. THE ANTENNA IS INSTALLED WITH 1 DEGREE OF MECHANICAL BEAM TILT DOWNWARD IN THE DIRECTION OF 215 DEGREES TRUE. THE ANTENNA HAS ELLIPTICAL POLARIZATION, WITH 16.67 PERCENT OF THE POWER APPLIED TO THE VERTICAL POLARIZATION COMPONENT. ELEVATION POWER GAIN OF THE ANTENNA IS 13.80 (11.38 DBD) IN THE HORIZONTAL POLARIZATION COMPONENT AND 2.80 (4.39 DBD) IN THE VERTICAL POLARIZATION COMPONENT AT THE VERTICAL BEAM MAXIMUM (1.0 DEGREE BELOW THE PLANE ORTHOGONAL TO THE AXIS OF THE ANTENNA AND THROUGH ITS RADIATION CENTER). AZIMUTH POWER GAIN OF THE ANTENNA IN THE HORIZONTAL POLARIZATION COMPONENT IS VIRTUALLY NIL (1.023 OR 0.10 DBD). THE MECHANICAL BEAM TILT CAUSES THE GAIN OF THE HORIZONTAL POLARIZATION COMPONENT TO VARY IN THE HORIZONTAL PLANE BETWEEN 13.80 (11.38 DBD) AT 35 DEGREES AZIMUTH AND 8.79 (9.44 DBD) AT 215 DEGREES AZIMUTH.

A PLOT OF THE AZIMUTHAL RADIATION PATTERN OF THE DTS SITE 1 ANTENNA IN RELATIVE FIELD VALUES OF THE HORIZONTAL POLARIZATION COMPONENT, PRIOR TO THE APPLICATION OF MECHANICAL BEAM TILT, (I.E., 1 DEGREE BELOW THE PLANE ORTHOGONAL TO THE AXIS OF THE ANTENNA AND THROUGH ITS RADIATION CENTER) IS INCLUDED AS FIGURE 3. THE AZIMUTHAL RADIATION PATTERN IN RELATIVE FIELD VALUES OF THE HORIZONTAL POLARIZATION COMPONENT IN THE HORIZONTAL PLANE, AFTER APPLICATION OF MECHANICAL BEAM TILT, IS INCLUDED AS FIGURE 4.   THE AZIMUTHAL POWER PATTERN OF THE HORIZONTAL POLARIZATION COMPONENT, EXPRESSED IN DECIBELS RELATIVE TO 1 KW (DBK), PRIOR TO THE APPLICATION OF MECHANICAL BEAM TILT, (I.E., 1 DEGREE BELOW THE PLANE ORTHOGONAL TO THE AXIS OF THE ANTENNA AND THROUGH ITS RADIATION CENTER) IS INCLUDED AS FIGURE 5. THE AZIMUTHAL POWER PATTERN OF THE HORIZONTAL POLARIZATION COMPONENT, EXPRESSED IN DECIBELS RELATIVE TO 1 KW (DBK) IN THE HORIZONTAL PLANE, IS PLOTTED IN FIGURE 6. TABULATED AZIMUTHAL FIELD AND POWER VALUES OF THE HORIZONTAL POLARIZATION COMPONENT DERIVED FROM THE DATA ARRAYS USED TO GENERATE FIGURES 3 THROUGH 6 ARE GIVEN IN FIGURE 7. THE ELEVATION RADIATION PATTERN IN RELATIVE FIELD VALUES OF THE HORIZONTAL POLARIZATION COMPONENT ALONG THE AXIS OF THE ANTENNA IS INCLUDED AS FIGURE 8. THE ELEVATION POWER PATTERN OF THE HORIZONTAL POLARIZATION COMPONENT, EXPRESSED IN DECIBELS RELATIVE TO 1 KW (DBK) ALONG THE AXIS OF THE ANTENNA, IS PLOTTED IN FIGURE 9. TABULATED ELEVATION FIELD AND POWER VALUES OF THE HORIZONTAL POLARIZATION COMPONENT DERIVED FROM THE DATA ARRAYS USED TO GENERATE FIGURES 8 &9 ARE GIVEN IN FIGURE 10.

BECAUSE OF THE MECHANICAL BEAM TILT APPLIED TO THE SITE 1 ANTENNA, ITS ELEVATION PATTERN VARIES WITH AZIMUTH, AND ITS AZIMUTH PATTERN VARIES WITH DEPRESSION ANGLE. THEREFORE, COMPLETE PATTERN DATA FOR THE ANTENNA FOR DTS SITE 1 IS BEING SUPPLIED THROUGH A COMPLEX ELEVATION PATTERN DATA FILE UPLOADED TO THE CDBS ELECTRONIC FILING SYSTEM. IN THAT FILE, DEPRESSION ANGLE VALUES ARE INCLUDED IN THE FIRST COLUMN, AND AZIMUTH VALUES ARE INCLUDED IN THE FIRST ROW. THE AZIMUTH AND ELEVATION PATTERN PLOTS AND TABULAR DATA SUPPLIED IN THIS TECHNICAL STATEMENT ARE FOR REFERENCE ONLY AND ARE INTENDED TO HELP IN VISUALIZATION OF THE CHARACTERISTICS OF THE ANTENNA. FULL SPECIFICATION OF THE ANTENNA PATTERN IS CONTAINED WHOLLY AND ONLY WITHIN THE ELEVATION PATTERN DATA FILE UPLOADED WITH THE FORM 301 APPLICATION.

IT SHOULD BE NOTED THAT, DUE TO LIMITATIONS IN THE FORM 301 DTS ENGINEERING PAGES IN THE CDBS ELECTRONIC FILING SYSTEM (EFS) AND BECAUSE THE VALUES IN THE AZIMUTH PATTERN RELATIVE FIELD DATA INPUT THERE ARE MULTIPLIED BY THE DATA IN THE ELEVATION PATTERN DATA FILE IN THE COMMISSIONS PROCESSING SOFTWARE, IT IS NOT POSSIBLE TO ENTER DATA INTO THE AZIMUTH PATTERN INPUT FIELDS THAT ARE REPRESENTATIVE OF THE HORIZONTAL PLANE PATTERN SUBSEQUENT TO INCLUSION OF THE EFFECTS OF MECHANICAL BEAM TILT. DOING SO WOULD RESULT IN DISTORTION OF THE ACTUAL PATTERN DATA AND LEAD TO INCORRECT ANALYSES OF THE PREDICTED INTERFERENCE FROM OR TO A STATION UNDER STUDY. MOREOVER, SINCE THE COMMISSIONS PROCESSING SOFTWARE DOES NOT HAVE THE ABILITY TO APPLY MECHANICAL BEAM TILT TO MORE THAN ONE ANTENNA IN A STUDY AND DOES NOT CURRENTLY APPLY MECHANICAL TILT IN A NON-DISTORTING WAY TO AN ANTENNA PATTERN, IT IS NECESSARY TO PUT DATA REPRESENTING THE RADIATION PATTERN OF EACH ANTENNA SUBSEQUENT TO APPLICATION OF MECHANICAL TILT INTO THE CORRESPONDING UPLOADED ELEVATION PATTERN DATA FILE, WHICH IS THE ONLY AVAILABLE MECHANISM THAT HAS SUFFICIENT DATA REPRESENTATION CAPACITY TO CARRY THE REQUIRED AMOUNT OF DATA. AS A RESULT OF ALL OF THIS, IT IS NECESSARY EITHER TO SET THE CHECK BOX RELATED TO THE AZIMUTH PATTERN INPUT FIELDS TO ''N/A'', WHICH PARENTHETICALLY ALSO INDICATES ''NON-DIRECTIONAL'', OR NOT TO CHECK THE ''N/A'' BOX BUT TO PUT VALUES OF 1.000 IN ALL OF THE AZIMUTH PATTERN DATA FIELDS. THE LATTER APPROACH AT LEAST INDICATES THAT THE ANTENNA IS DIRECTIONAL AND THEREFORE WAS TAKEN IN THE INSTANT APPLICATION FOR EACH OF THE DTS SITES AND THEIR ANTENNA PATTERNS.

THE PROPOSED DTS SITE 2 (TABLE MOUNTAIN) ANTENNA WILL HAVE COLUMNS OF PANELS FACING 62 AND 327 DEGREES TRUE, WITH RESULTING MAJOR AZIMUTH LOBES AT 15, 61, AND 328 DEGREES TRUE. IT WILL HAVE AN ELEVATION PATTERN WITH ITS MAIN LOBE 3 DEGREES BELOW THE PLANE ORTHOGONAL TO THE AXIS OF THE ANTENNA AND THROUGH ITS RADIATION CENTER. THE ELEVATION PATTERN ALSO WILL CONTAIN A NOTCH ABOVE THE MAIN LOBE AT 0.2 DEGREE ABOVE THE PLANE ORTHOGONAL TO THE AXIS OF THE ANTENNA AND THROUGH ITS RADIATION CENTER. MECHANICAL BEAM TILT OF 2.3 DEGREES DOWNWARD WILL BE APPLIED TO THE ANTENNA AT A BEARING OF 204 DEGREES TRUE. THIS WILL RESULT IN THE MAIN BEAM BEING LIFTED TO A DEPRESSION ANGLE OF 0.7 DEGREES TOWARD A BEARING OF 24 DEGREES TRUE AND BEING PUSHED DOWN TO A DEPRESSION ANGLE OF 5.3 DEGREES AT THE 204-DEGREE BEARING. IT ALSO WILL RESULT IN THE NOTCH ABOVE THE MAIN BEAM BEING PUSHED DOWN TO A DEPRESSION ANGLE OF 2.1 DEGREES AT THE 204-DEGREE BEARING.

THE CHARACTERISTICS AND PARAMETERS OF DTS SITE 2 ARE FULLY DESCRIBED IN FIGURE 1B. THE DTS SITE 2 ANTENNA WILL HAVE CIRCULAR POLARIZATION, WITH EQUAL POWER APPLIED TO BOTH THE HORIZONTAL AND VERTICAL POLARIZATION COMPONENTS; THUS THE EFFECTIVE RADIATED POWER OF EACH INDIVIDUAL COMPONENT IS BASED ON HALF THE POWER INPUT TO THE ANTENNA. ELEVATION POWER GAIN OF THE ANTENNA DESIGN FOR DTS SITE 2, AT THE AZIMUTH OF BEAM MAXIMUM (61 DEGREES) AND IN EACH OF THE HORIZONTAL AND VERTICAL POLARIZATION COMPONENTS, IS 12.90 (11.12 DBD) AT THE BEAM MAXIMUM (3.0 DEGREES BELOW THE PLANE ORTHOGONAL TO THE AXIS OF THE ANTENNA AND THROUGH ITS RADIATION CENTER) AND JUST OVER 0.0029 (25.36 DBD) AT THE NULL ABOVE THE MAIN BEAM (0.2 DEGREES ABOVE THE PLANE ORTHOGONAL TO THE AXIS OF THE ANTENNA AND THROUGH ITS RADIATION CENTER). THE AZIMUTH POWER GAIN, AT THE DEPRESSION ANGLE OF BEAM MAXIMUM (3.0 DEGREES BELOW THE PLANE ORTHOGONAL TO THE AXIS OF THE ANTENNA AND THROUGH ITS RADIATION CENTER) AND IN EACH OF THE HORIZONTAL AND VERTICAL POLARIZATION COMPONENTS IS 2.90 (4.62 DB). THE TOTAL POWER GAIN IN EACH OF THE HORIZONTAL AND VERTICAL POLARIZATION COMPONENTS IN THE MAIN BEAM IS 37.41 (15.73 DBD). THE MECHANICAL BEAM TILT CAUSES THE GAIN OF EACH OF THE HORIZONTAL AND VERTICAL POLARIZATION COMPONENTS TO VARY IN THE HORIZONTAL PLANE BETWEEN 23.61 (13.73 DBD) AT 53 DEGREES AZIMUTH AND 0.000002647 ( 55.77 DBD) AT 194 DEGREES AZIMUTH.

A PLOT OF THE DTS SITE 2 ANTENNA AZIMUTHAL RADIATION PATTERN IN RELATIVE FIELD VALUES, AT THE DEPRESSION ANGLE HAVING MAXIMUM FIELD (3.0 DEGREES BELOW THE PLANE ORTHOGONAL TO THE AXIS OF THE ANTENNA AND THROUGH ITS RADIATION CENTER), IS INCLUDED AS FIGURE 11. THE AZIMUTHAL POWER PATTERN EXPRESSED IN DECIBELS RELATIVE TO 1 KW (DBK), AT THE DEPRESSION ANGLE HAVING MAXIMUM POWER (ALSO 3.0 DEGREES BELOW THE PLANE ORTHOGONAL TO THE AXIS OF THE ANTENNA AND THROUGH ITS RADIATION CENTER), IS PLOTTED IN FIGURE 12. THE TABULATED AZIMUTHAL FIELD AND POWER VALUES ARE GIVEN IN FIGURE 13. THE ELEVATION RADIATION PATTERN IN RELATIVE FIELD VALUES ALONG THE AXIS OF THE ANTENNA, IN THE AZIMUTHAL DIRECTION HAVING MAXIMUM FIELD (61 DEGREES), IS INCLUDED AS FIGURE 14.

THE TABULATED ELEVATION FIELD AND POWER VALUES ARE GIVEN IN FIGURE 16.

BECAUSE OF THE MECHANICAL BEAM TILT APPLIED TO THE DTS SITE 2 ANTENNA, ITS ELEVATION PATTERN VARIES WITH AZIMUTH, AND ITS AZIMUTH PATTERN VARIES WITH DEPRESSION ANGLE. THEREFORE, COMPLETE PATTERN DATA FOR THE ANTENNA FOR DTS SITE 2 ARE BEING SUPPLIED THROUGH A COMPLEX ELEVATION PATTERN DATA FILE UPLOADED TO THE CDBS ELECTRONIC FILING SYSTEM. IN THAT FILE, DEPRESSION ANGLE VALUES ARE INCLUDED IN THE FIRST COLUMN, AND AZIMUTH VALUES ARE INCLUDED IN THE FIRST ROW. THE AZIMUTH AND ELEVATION PATTERN PLOTS AND TABULAR DATA SUPPLIED IN THIS TECHNICAL STATEMENT ARE FOR REFERENCE ONLY AND ARE INTENDED TO HELP IN VISUALIZATION OF THE CHARACTERISTICS OF THE ANTENNA. FULL SPECIFICATION OF THE ANTENNA PATTERN IS CONTAINED WHOLLY AND ONLY WITHIN THE ELEVATION PATTERN DATA FILE UPLOADED WITH THE FORM 301 APPLICATION. IT SHOULD BE NOTED THAT THE LIMITATIONS OF THE CDBS EFS FORM 301 DTS ENGINEERING WEB PAGE REGARDING INCLUSION OF AZIMUTH PATTERN RELATIVE FIELD VALUES AND THE RELATED CHECK BOX, DESCRIBED ABOVE WITH RESPECT TO THE DTS SITE 1 ANTENNA, APPLY EQUALLY WITH RESPECT TO THE DTS SITE 2 ANTENNA AND THAT THE SAME APPROACH TAKEN FOR SITE 1 HAS BEEN FOLLOWED FOR SITE 2.

THE PROPOSED DTS SITES 3 AND 4 ANTENNAS (BOTH OF WHICH WILL BE AT OAT MOUNTAIN) WILL BE COMPOSED OF SINGLE COLUMNS OF PANELS 6 FOR DTS SITE 3 AND 4 FOR DTS SITE 4. THERE WILL BE NO ELECTRICAL BEAM TILT APPLIED TO THE ELEVATION PATTERN OF EITHER ANTENNA; ONLY MECHANICAL BEAM TILT WILL BE APPLIED TO EACH OF THEM. THE DTS SITE 3 ANTENNA WILL BE ORIENTED WITH ITS MAIN BEAM TOWARD AN AZIMUTH OF 255 DEGREES TRUE AND 1.5 DEGREES BELOW THE HORIZONTAL AT THE SAME HEADING. THE DTS SITE 4 ANTENNA WILL BE MOUNTED 20 METERS BELOW THE DTS SITE 3 ANTENNA ON THE SAME TOWER. IT WILL BE ORIENTED WITH ITS MAIN BEAM TOWARD AN AZIMUTH OF 15 DEGREES AND 2.0 DEGREES BELOW THE HORIZONTAL AT THE SAME HEADING.

THE CHARACTERISTICS AND PARAMETERS OF DTS SITES 3 AND 4 ARE FULLY DESCRIBED IN FIGURES 1C AND 1D, RESPECTIVELY. THEIR ANTENNAS WILL HAVE CIRCULAR POLARIZATION, WITH EQUAL POWER APPLIED TO BOTH THE HORIZONTAL AND VERTICAL POLARIZATION COMPONENTS; THUS, THE EFFECTIVE RADIATED POWER OF EACH INDIVIDUAL COMPONENT IS BASED ON HALF THE POWER INPUT TO ITS RESPECTIVE ANTENNA. ELEVATION POWER GAIN OF THE ANTENNA DESIGN FOR DTS SITE 3, AT THE AZIMUTH OF BEAM MAXIMUM (255 DEGREES) AND IN EACH OF THE HORIZONTAL AND VERTICAL POLARIZATION COMPONENTS, IS 14.24 (11.54 DBD) AT THE BEAM MAXIMUM (IN THE PLANE ORTHOGONAL TO THE AXIS OF THE ANTENNA AND THROUGH ITS RADIATION CENTER). THE AZIMUTH POWER GAIN, AT THE DEPRESSION ANGLE OF BEAM MAXIMUM (IN THE PLANE ORTHOGONAL TO THE AXIS OF THE ANTENNA AND THROUGH ITS RADIATION CENTER) AND IN EACH OF THE HORIZONTAL AND VERTICAL POLARIZATION COMPONENTS IS 5.63 (7.51 DB). THE TOTAL POWER GAIN IN EACH OF THE HORIZONTAL AND VERTICAL POLARIZATION COMPONENTS IN THE MAIN BEAM IS 80.17 (19.04 DBD). THE MECHANICAL BEAM TILT CAUSES THE GAIN OF EACH OF THE HORIZONTAL AND VERTICAL POLARIZATION COMPONENTS TO VARY IN THE HORIZONTAL PLANE BETWEEN 53.80 (17.31 DBD) AT 255 DEGREES AZIMUTH AND 0.27878 ( 5.55 DBD) AT BOTH 43 AND 107 DEGREES AZIMUTH.

ELEVATION POWER GAIN OF THE ANTENNA DESIGN FOR DTS SITE 4, AT THE AZIMUTH OF BEAM MAXIMUM (15 DEGREES) AND IN EACH OF THE HORIZONTAL AND VERTICAL POLARIZATION COMPONENTS, IS 9.50 (9.78 DBD) AT THE BEAM MAXIMUM (IN THE PLANE ORTHOGONAL TO THE AXIS OF THE ANTENNA AND THROUGH ITS RADIATION CENTER). THE AZIMUTH POWER GAIN, AT THE DEPRESSION ANGLE OF BEAM MAXIMUM (IN THE PLANE ORTHOGONAL TO THE AXIS OF THE ANTENNA AND THROUGH ITS RADIATION CENTER) AND IN EACH OF THE HORIZONTAL AND VERTICAL POLARIZATION COMPONENTS IS 5.63 (7.51 DB). THE TOTAL POWER GAIN IN EACH OF THE HORIZONTAL AND VERTICAL POLARIZATION COMPONENTS IN THE MAIN BEAM IS 53.49 (17.28 DBD). THE MECHANICAL BEAM TILT CAUSES THE GAIN OF EACH OF THE HORIZONTAL AND VERTICAL POLARIZATION COMPONENTS TO VARY IN THE HORIZONTAL PLANE BETWEEN 38.83 (15.89 DBD) AT 15 DEGREES AZIMUTH AND 0.1965 ( 7.07 DBD) AT BOTH 163 AND 227 DEGREES AZIMUTH.

PLOTS OF THE AZIMUTHAL RADIATION PATTERNS OF THE DTS SITES 3 & 4 ANTENNAS IN RELATIVE FIELD VALUES, AT THE DEPRESSION ANGLES HAVING MAXIMUM FIELD (IN THE PLANES ORTHOGONAL TO THE AXES OF THE ANTENNAS AND THROUGH THEIR RADIATION CENTERS), ARE INCLUDED AS FIGURES 17A AND 17B.

THE FACILITIES REQUESTED IN THIS APPLICATION INCLUDE CONTINUED OPERATION AT 665 KW ERP AT A HEIGHT ABOVE AVERAGE TERRAIN OF 991 METERS AT THE MT WILSON SITE, OPERATION AT 50 KW ERP AT 696.5 METERS HAAT AT TABLE MOUNTAIN, AND OPERATION AT 25.1 KW AT 588.5 METERS HAAT AND AT 16.74 KW AT 568.5 METERS HAAT AT OAT MOUNTAIN. THE CURRENTLY AUTHORIZED FACILITY AT THE MT WILSON SITE MEETS THE REQUIREMENTS OF SECTION 73.622(F)(5), AS ITS COMBINATION OF POWER AND ANTENNA HEIGHT DOES NOT PRODUCE A PREDICTED NOISE-LIMITED CONTOUR THE AREA OF WHICH EXCEEDS THAT OF THE LARGEST SUCH AREA PRODUCED BY ANOTHER STATION IN THE SAME MARKET. THE RELATIONSHIPS BETWEEN THE PARAMETERS IN THE CASES OF THE GAP-FILLER TRANSMITTERS RESULT IN POWER/HEIGHT COMBINATIONS THAT MEET THE REQUIREMENTS FOR MAXIMUM ALLOWABLE FACILITIES SPECIFIED BY THE TABLE IN SECTION 73.622(F)(8)(I) OF THE COMMISSIONS RULES. THE BASIC CHARACTERISTICS OF EACH OF THE TRANSMITTERS PROPOSED IN THE KNBC DTS NETWORK ARE GIVEN IN FIGURES 1A, 1B, 1C, AND 1D AT THE END OF THIS TECHNICAL STATEMENT AND IN THE RELATED DTS ENGINEERING PORTIONS OF THE FORM 301 APPLICATION ONE FOR EACH TRANSMITTER.

THREE FUNDAMENTAL ANTENNA DESIGNS ARE PROPOSED FOR USE IN THE KNBC DTS NETWORK. THE MT WILSON (DTS SITE 1) ANTENNA IS A RELATIVELY CONVENTIONAL, OMNIDIRECTIONAL, CENTER-FED, SLOTTED COAXIAL DESIGN. IT HAS ONE DEGREE OF ELECTRICAL BEAM TILT AND IS INSTALLED WITH ONE DEGREE OF MECHANICAL BEAM TILT DOWNWARD TOWARD 215 DEGREES.

THE COMBINATION OF THE ELECTRICAL BEAM TILT AND THE NOTCH WILL PERMIT THE APPLICATION OF MECHANICAL BEAM TILT TO THE ANTENNA IN SUCH A WAY THAT THE FORWARD LOBES WILL BE ORIENTED TO A RELATIVELY CONVENTIONAL DEPRESSION ANGLE (0.7 DEGREES), WHILE THE BACK LOBES WILL BE DRIVEN INTO THE GROUND, WITH THE NOTCH OCCURRING AT A DEPRESSION ANGLE THAT WILL PERMIT SUBSTANTIAL REDUCTION IN POWER TOWARD A NEARBY SCIENTIFIC INSTALLATION. THIS COMBINATION OF FACTORS IS DISCUSSED IN MORE DETAIL BELOW.

THE ANTENNA DESIGNS AT THE OAT MOUNTAIN SITE WILL BE RELATIVELY SIMPLE, SINGLE-COLUMN ARRAYS OF SIX PANELS AND FOUR PANELS EACH FOR DTS SITES 3 AND 4, RESPECTIVELY. EACH WILL HAVE A SINGLE MAIN LOBE IN ITS AZIMUTH PATTERN. NO ELECTRICAL BEAM TILT WILL BE USED, WITH ONLY MECHANICAL BEAM TILT APPLIED TO CONTROL THE EXTENT OF SIGNAL PROJECTION FROM THE ANTENNAS.

ALL FOUR TRANSMITTERS IN THE PROPOSED DTS NETWORK ARE LOCATED WITHIN THE KNBC ''LARGEST STATION'' ALTERNATIVE TO THE TABLE OF DISTANCES AREA (DISCUSSED IN DETAIL BELOW), CONSEQUENTLY MEETING THE REQUIREMENTS OF SECTION 73.626(F)(6).

THE CHARACTERISTICS OF THE DTS SITE 1 (MT WILSON) FACILITY ARE FULLY DESCRIBED IN FIGURE 1A. THE ANTENNA IS INSTALLED WITH 1 DEGREE OF MECHANICAL BEAM TILT DOWNWARD IN THE DIRECTION OF 215 DEGREES TRUE. THE ANTENNA HAS ELLIPTICAL POLARIZATION, WITH 16.67 PERCENT OF THE POWER APPLIED TO THE VERTICAL POLARIZATION COMPONENT. ELEVATION POWER GAIN OF THE ANTENNA IS 13.80 (11.38 DBD) IN THE HORIZONTAL POLARIZATION COMPONENT AND 2.80 (4.39 DBD) IN THE VERTICAL POLARIZATION COMPONENT AT THE VERTICAL BEAM MAXIMUM (1.0 DEGREE BELOW THE PLANE ORTHOGONAL TO THE AXIS OF THE ANTENNA AND THROUGH ITS RADIATION CENTER). AZIMUTH POWER GAIN OF THE ANTENNA IN THE HORIZONTAL POLARIZATION COMPONENT IS VIRTUALLY NIL (1.023 OR 0.10 DBD). THE MECHANICAL BEAM TILT CAUSES THE GAIN OF THE HORIZONTAL POLARIZATION COMPONENT TO VARY IN THE HORIZONTAL PLANE BETWEEN 13.80 (11.38 DBD) AT 35 DEGREES AZIMUTH AND 8.79 (9.44 DBD) AT 215 DEGREES AZIMUTH.

THE AZIMUTH AND ELEVATION PATTERN PLOTS AND TABULAR DATA SUPPLIED IN THIS TECHNICAL STATEMENT ARE FOR REFERENCE ONLY AND ARE INTENDED TO HELP IN VISUALIZATION OF THE CHARACTERISTICS OF THE ANTENNA. FULL SPECIFICATION OF THE ANTENNA PATTERN IS CONTAINED WHOLLY AND ONLY WITHIN THE ELEVATION PATTERN DATA FILE UPLOADED WITH THE FORM 301 APPLICATION.

IT SHOULD BE NOTED THAT, DUE TO LIMITATIONS IN THE FORM 301 DTS ENGINEERING PAGES IN THE CDBS ELECTRONIC FILING SYSTEM (EFS) AND BECAUSE THE VALUES IN THE AZIMUTH PATTERN RELATIVE FIELD DATA INPUT THERE ARE MULTIPLIED BY THE DATA IN THE ELEVATION PATTERN DATA FILE IN THE COMMISSIONS PROCESSING SOFTWARE, IT IS NOT POSSIBLE TO ENTER DATA INTO THE AZIMUTH PATTERN INPUT FIELDS THAT ARE REPRESENTATIVE OF THE HORIZONTAL PLANE PATTERN SUBSEQUENT TO INCLUSION OF THE EFFECTS OF MECHANICAL BEAM TILT. DOING SO WOULD RESULT IN DISTORTION OF THE ACTUAL PATTERN DATA AND LEAD TO INCORRECT ANALYSES OF THE PREDICTED INTERFERENCE FROM OR TO A STATION UNDER STUDY. MOREOVER, SINCE THE COMMISSIONS PROCESSING SOFTWARE DOES NOT HAVE THE ABILITY TO APPLY MECHANICAL BEAM TILT TO MORE THAN ONE ANTENNA IN A STUDY AND DOES NOT CURRENTLY APPLY MECHANICAL TILT IN A NON-DISTORTING WAY TO AN ANTENNA PATTERN, IT IS NECESSARY TO PUT DATA REPRESENTING THE RADIATION PATTERN OF EACH ANTENNA SUBSEQUENT TO APPLICATION OF MECHANICAL TILT INTO THE CORRESPONDING UPLOADED ELEVATION PATTERN DATA FILE, WHICH IS THE ONLY AVAILABLE MECHANISM THAT HAS SUFFICIENT DATA REPRESENTATION CAPACITY TO CARRY THE REQUIRED AMOUNT OF DATA. AS A RESULT OF ALL OF THIS, IT IS NECESSARY EITHER TO SET THE CHECK BOX RELATED TO THE AZIMUTH PATTERN INPUT FIELDS TO ''N/A'', WHICH PARENTHETICALLY ALSO INDICATES ''NON-DIRECTIONAL'', OR NOT TO CHECK THE ''N/A'' BOX BUT TO PUT VALUES OF 1.000 IN ALL OF THE AZIMUTH PATTERN DATA FIELDS. THE LATTER APPROACH AT LEAST INDICATES THAT THE ANTENNA IS DIRECTIONAL AND THEREFORE WAS TAKEN IN THE INSTANT APPLICATION FOR EACH OF THE DTS SITES AND THEIR ANTENNA PATTERNS.

THE PROPOSED DTS SITE 2 (TABLE MOUNTAIN) ANTENNA WILL HAVE COLUMNS OF PANELS FACING 62 AND 327 DEGREES TRUE, WITH RESULTING MAJOR AZIMUTH LOBES AT 15, 61, AND 328 DEGREES TRUE. IT WILL HAVE AN ELEVATION PATTERN WITH ITS MAIN LOBE 3 DEGREES BELOW THE PLANE ORTHOGONAL TO THE AXIS OF THE ANTENNA AND THROUGH ITS RADIATION CENTER. THE ELEVATION PATTERN ALSO WILL CONTAIN A NOTCH ABOVE THE MAIN LOBE AT 0.2 DEGREE ABOVE THE PLANE ORTHOGONAL TO THE AXIS OF THE ANTENNA AND THROUGH ITS RADIATION CENTER. MECHANICAL BEAM TILT OF 2.3 DEGREES DOWNWARD WILL BE APPLIED TO THE ANTENNA AT A BEARING OF 204 DEGREES TRUE. THIS WILL RESULT IN THE MAIN BEAM BEING LIFTED TO A DEPRESSION ANGLE OF 0.7 DEGREES TOWARD A BEARING OF 24 DEGREES TRUE AND BEING PUSHED DOWN TO A DEPRESSION ANGLE OF 5.3 DEGREES AT THE 204-DEGREE BEARING. IT ALSO WILL RESULT IN THE NOTCH ABOVE THE MAIN BEAM BEING PUSHED DOWN TO A DEPRESSION ANGLE OF 2.1 DEGREES AT THE 204-DEGREE BEARING.

THE CHARACTERISTICS AND PARAMETERS OF DTS SITE 2 ARE FULLY DESCRIBED IN FIGURE 1B. THE DTS SITE 2 ANTENNA WILL HAVE CIRCULAR POLARIZATION, WITH EQUAL POWER APPLIED TO BOTH THE HORIZONTAL AND VERTICAL POLARIZATION COMPONENTS; THUS THE EFFECTIVE RADIATED POWER OF EACH INDIVIDUAL COMPONENT IS BASED ON HALF THE POWER INPUT TO THE ANTENNA. ELEVATION POWER GAIN OF THE ANTENNA DESIGN FOR DTS SITE 2, AT THE AZIMUTH OF BEAM MAXIMUM (61 DEGREES) AND IN EACH OF THE HORIZONTAL AND VERTICAL POLARIZATION COMPONENTS, IS 12.90 (11.12 DBD) AT THE BEAM MAXIMUM (3.0 DEGREES BELOW THE PLANE ORTHOGONAL TO THE AXIS OF THE ANTENNA AND THROUGH ITS RADIATION CENTER) AND JUST OVER 0.0029 (25.36 DBD) AT THE NULL ABOVE THE MAIN BEAM (0.2 DEGREES ABOVE THE PLANE ORTHOGONAL TO THE AXIS OF THE ANTENNA AND THROUGH ITS RADIATION CENTER). THE AZIMUTH POWER GAIN, AT THE DEPRESSION ANGLE OF BEAM MAXIMUM (3.0 DEGREES BELOW THE PLANE ORTHOGONAL TO THE AXIS OF THE ANTENNA AND THROUGH ITS RADIATION CENTER) AND IN EACH OF THE HORIZONTAL AND VERTICAL POLARIZATION COMPONENTS IS 2.90 (4.62 DB). THE TOTAL POWER GAIN IN EACH OF THE HORIZONTAL AND VERTICAL POLARIZATION COMPONENTS IN THE MAIN BEAM IS 37.41 (15.73 DBD). THE MECHANICAL BEAM TILT CAUSES THE GAIN OF EACH OF THE HORIZONTAL AND VERTICAL POLARIZATION COMPONENTS TO VARY IN THE HORIZONTAL PLANE BETWEEN 23.61 (13.73 DBD) AT 53 DEGREES AZIMUTH AND 0.000002647 ( 55.77 DBD) AT 194 DEGREES AZIMUTH.

THE TABULATED ELEVATION FIELD AND POWER VALUES ARE GIVEN IN FIGURE 16.

BECAUSE OF THE MECHANICAL BEAM TILT APPLIED TO THE DTS SITE 2 ANTENNA, ITS ELEVATION PATTERN VARIES WITH AZIMUTH, AND ITS AZIMUTH PATTERN VARIES WITH DEPRESSION ANGLE. THEREFORE, COMPLETE PATTERN DATA FOR THE ANTENNA FOR DTS SITE 2 ARE BEING SUPPLIED THROUGH A COMPLEX ELEVATION PATTERN DATA FILE UPLOADED TO THE CDBS ELECTRONIC FILING SYSTEM.

THE PROPOSED DTS SITES 3 AND 4 ANTENNAS (BOTH OF WHICH WILL BE AT OAT MOUNTAIN) WILL BE COMPOSED OF SINGLE COLUMNS OF PANELS 6 FOR DTS SITE 3 AND 4 FOR DTS SITE 4. THERE WILL BE NO ELECTRICAL BEAM TILT APPLIED TO THE ELEVATION PATTERN OF EITHER ANTENNA; ONLY MECHANICAL BEAM TILT WILL BE APPLIED TO EACH OF THEM. THE DTS SITE 3 ANTENNA WILL BE ORIENTED WITH ITS MAIN BEAM TOWARD AN AZIMUTH OF 255 DEGREES TRUE AND 1.5 DEGREES BELOW THE HORIZONTAL AT THE SAME HEADING. THE DTS SITE 4 ANTENNA WILL BE MOUNTED 20 METERS BELOW THE DTS SITE 3 ANTENNA ON THE SAME TOWER. IT WILL BE ORIENTED WITH ITS MAIN BEAM TOWARD AN AZIMUTH OF 15 DEGREES AND 2.0 DEGREES BELOW THE HORIZONTAL AT THE SAME HEADING.

THE CHARACTERISTICS AND PARAMETERS OF DTS SITES 3 AND 4 ARE FULLY DESCRIBED IN FIGURES 1C AND 1D, RESPECTIVELY. THEIR ANTENNAS WILL HAVE CIRCULAR POLARIZATION, WITH EQUAL POWER APPLIED TO BOTH THE HORIZONTAL AND VERTICAL POLARIZATION COMPONENTS; THUS, THE EFFECTIVE RADIATED POWER OF EACH INDIVIDUAL COMPONENT IS BASED ON HALF THE POWER INPUT TO ITS RESPECTIVE ANTENNA. ELEVATION POWER GAIN OF THE ANTENNA DESIGN FOR DTS SITE 3, AT THE AZIMUTH OF BEAM MAXIMUM (255 DEGREES) AND IN EACH OF THE HORIZONTAL AND VERTICAL POLARIZATION COMPONENTS, IS 14.24 (11.54 DBD) AT THE BEAM MAXIMUM (IN THE PLANE ORTHOGONAL TO THE AXIS OF THE ANTENNA AND THROUGH ITS RADIATION CENTER). THE AZIMUTH POWER GAIN, AT THE DEPRESSION ANGLE OF BEAM MAXIMUM (IN THE PLANE ORTHOGONAL TO THE AXIS OF THE ANTENNA AND THROUGH ITS RADIATION CENTER) AND IN EACH OF THE HORIZONTAL AND VERTICAL POLARIZATION COMPONENTS IS 5.63 (7.51 DB). THE TOTAL POWER GAIN IN EACH OF THE HORIZONTAL AND VERTICAL POLARIZATION COMPONENTS IN THE MAIN BEAM IS 80.17 (19.04 DBD). THE MECHANICAL BEAM TILT CAUSES THE GAIN OF EACH OF THE HORIZONTAL AND VERTICAL POLARIZATION COMPONENTS TO VARY IN THE HORIZONTAL PLANE BETWEEN 53.80 (17.31 DBD) AT 255 DEGREES AZIMUTH AND 0.27878 ( 5.55 DBD) AT BOTH 43 AND 107 DEGREES AZIMUTH.

ELEVATION POWER GAIN OF THE ANTENNA DESIGN FOR DTS SITE 4, AT THE AZIMUTH OF BEAM MAXIMUM (15 DEGREES) AND IN EACH OF THE HORIZONTAL AND VERTICAL POLARIZATION COMPONENTS, IS 9.50 (9.78 DBD) AT THE BEAM MAXIMUM (IN THE PLANE ORTHOGONAL TO THE AXIS OF THE ANTENNA AND THROUGH ITS RADIATION CENTER). THE AZIMUTH POWER GAIN, AT THE DEPRESSION ANGLE OF BEAM MAXIMUM (IN THE PLANE ORTHOGONAL TO THE AXIS OF THE ANTENNA AND THROUGH ITS RADIATION CENTER) AND IN EACH OF THE HORIZONTAL AND VERTICAL POLARIZATION COMPONENTS IS 5.63 (7.51 DB). THE TOTAL POWER GAIN IN EACH OF THE HORIZONTAL AND VERTICAL POLARIZATION COMPONENTS IN THE MAIN BEAM IS 53.49 (17.28 DBD). THE MECHANICAL BEAM TILT CAUSES THE GAIN OF EACH OF THE HORIZONTAL AND VERTICAL POLARIZATION COMPONENTS TO VARY IN THE HORIZONTAL PLANE BETWEEN 38.83 (15.89 DBD) AT 15 DEGREES AZIMUTH AND 0.1965 ( 7.07 DBD) AT BOTH 163 AND 227 DEGREES AZIMUTH.

THE TABULATED ELEVATION FIELD AND POWER VALUES ARE GIVEN IN FIGURE 22.

BECAUSE OF THE MECHANICAL BEAM TILT APPLIED TO THE DTS SITES 3 & 4 ANTENNAS, THEIR ELEVATION PATTERNS VARY WITH AZIMUTH, AND THEIR AZIMUTH PATTERNS VARY WITH DEPRESSION ANGLE. THEREFORE, COMPLETE PATTERN DATA FOR THE ANTENNAS FOR DTS SITES 3 & 4 ARE BEING SUPPLIED THROUGH COMPLEX ELEVATION PATTERN DATA FILES UPLOADED TO THE CDBS ELECTRONIC FILING SYSTEM. IN THOSE FILES, DEPRESSION ANGLE VALUES ARE INCLUDED IN THE FIRST COLUMNS, AND AZIMUTH VALUES ARE INCLUDED IN THE FIRST ROWS. THE AZIMUTH AND ELEVATION PATTERN PLOTS AND TABULAR DATA SUPPLIED IN THIS TECHNICAL STATEMENT ARE FOR REFERENCE ONLY AND ARE INTENDED TO HELP IN VISUALIZATION OF THE CHARACTERISTICS OF THE ANTENNAS. FULL SPECIFICATIONS OF THE ANTENNA PATTERNS ARE CONTAINED WHOLLY AND ONLY WITHIN THE ELEVATION PATTERN DATA FILES UPLOADED WITH THE FORM 301 APPLICATION.

FACILITIES -- RELEVANT TO DTS SITE 4

[EXTRACT OF FACILITIES SECTION + CHARTS & TABLES RELEVANT TO DTS SITE 4 FROM TECHNICAL STATEMENT ATTACHED TO EXHIBIT 51.]

THE FACILITIES REQUESTED IN THIS APPLICATION INCLUDE CONTINUED OPERATION AT 665 KW ERP AT A HEIGHT ABOVE AVERAGE TERRAIN OF 991 METERS AT THE MT WILSON SITE, OPERATION AT 50 KW ERP AT 696.5 METERS HAAT AT TABLE MOUNTAIN, AND OPERATION AT 25.1 KW AT 588.5 METERS HAAT AND AT 16.74 KW AT 568.5 METERS HAAT AT OAT MOUNTAIN. THE CURRENTLY AUTHORIZED FACILITY AT THE MT WILSON SITE MEETS THE REQUIREMENTS OF SECTION 73.622(F)(5), AS ITS COMBINATION OF POWER AND ANTENNA HEIGHT DOES NOT PRODUCE A PREDICTED NOISE-LIMITED CONTOUR THE AREA OF WHICH EXCEEDS THAT OF THE LARGEST SUCH AREA PRODUCED BY ANOTHER STATION IN THE SAME MARKET. THE RELATIONSHIPS BETWEEN THE PARAMETERS IN THE CASES OF THE GAP-FILLER TRANSMITTERS RESULT IN POWER/HEIGHT COMBINATIONS THAT MEET THE REQUIREMENTS FOR MAXIMUM ALLOWABLE FACILITIES SPECIFIED BY THE TABLE IN SECTION 73.622(F)(8)(I) OF THE COMMISSIONS RULES. THE BASIC CHARACTERISTICS OF EACH OF THE TRANSMITTERS PROPOSED IN THE KNBC DTS NETWORK ARE GIVEN IN FIGURES 1A, 1B, 1C, AND 1D AT THE END OF THIS TECHNICAL STATEMENT AND IN THE RELATED DTS ENGINEERING PORTIONS OF THE FORM 301 APPLICATION ONE FOR EACH TRANSMITTER.

THREE FUNDAMENTAL ANTENNA DESIGNS ARE PROPOSED FOR USE IN THE KNBC DTS NETWORK. THE MT WILSON (DTS SITE 1) ANTENNA IS A RELATIVELY CONVENTIONAL, OMNIDIRECTIONAL, CENTER-FED, SLOTTED COAXIAL DESIGN. IT HAS ONE DEGREE OF ELECTRICAL BEAM TILT AND IS INSTALLED WITH ONE DEGREE OF MECHANICAL BEAM TILT DOWNWARD TOWARD 215 DEGREES. IT HAS BEEN IN SERVICE FOR KNBC SINCE THE STATION FIRST INITIATED DIGITAL TRANSMISSION IN 1998.

THE ANTENNA DESIGN AT THE TABLE MOUNTAIN SITE (DTS SITE 2) WILL BE A PANEL ARRAY, USING BROADBAND PANELS AND A CORPORATE FEED. IT WILL CONSIST OF A TOTAL OF SIXTEEN PANELS IN TWO COLUMNS OF EIGHT EACH AND WILL HAVE THREE MAIN LOBES IN ITS AZIMUTH PATTERN. A SIGNIFICANT AMOUNT OF ELECTRICAL BEAM TILT WILL BE USED, WITH A SUBSTANTIAL NOTCH IN THE RADIATION ABOVE THE MAIN BEAM. THE COMBINATION OF THE ELECTRICAL BEAM TILT AND THE NOTCH WILL PERMIT THE APPLICATION OF MECHANICAL BEAM TILT TO THE ANTENNA IN SUCH A WAY THAT THE FORWARD LOBES WILL BE ORIENTED TO A RELATIVELY CONVENTIONAL DEPRESSION ANGLE (0.7 DEGREES), WHILE THE BACK LOBES WILL BE DRIVEN INTO THE GROUND, WITH THE NOTCH OCCURRING AT A DEPRESSION ANGLE THAT WILL PERMIT SUBSTANTIAL REDUCTION IN POWER TOWARD A NEARBY SCIENTIFIC INSTALLATION. THIS COMBINATION OF FACTORS IS DISCUSSED IN MORE DETAIL BELOW.

THE ANTENNA DESIGNS AT THE OAT MOUNTAIN SITE WILL BE RELATIVELY SIMPLE, SINGLE-COLUMN ARRAYS OF SIX PANELS AND FOUR PANELS EACH FOR DTS SITES 3 AND 4, RESPECTIVELY. EACH WILL HAVE A SINGLE MAIN LOBE IN ITS AZIMUTH PATTERN. NO ELECTRICAL BEAM TILT WILL BE USED, WITH ONLY MECHANICAL BEAM TILT APPLIED TO CONTROL THE EXTENT OF SIGNAL PROJECTION FROM THE ANTENNAS.

A PLOT OF THE PROPOSED PNLCS OF THE FOUR TRANSMITTERS IS PROVIDED IN FIGURE 2, WHERE THE EXISTING SITE 1 CONTOUR IS IN ORANGE, THE PROPOSED SITE 2 CONTOUR IS IN OLIVE, THE PROPOSED SITE 3 CONTOUR IS IN GREEN, AND THE PROPOSED SITE 4 CONTOUR IS IN VIOLET. IN ITS CURRENT CONFIGURATION, THE MAIN, MT WILSON TRANSMITTER FACILITY AUTHORIZED BY THE EXISTING CONSTRUCTION PERMIT (HEREIN, DTS SITE 1) ALREADY COVERS THE ENTIRE AUTHORIZED SERVICE AREA OF THE STATION; THUS, THE REQUIREMENTS OF SECTION 73.626(F)(1) WOULD BE MET BY THAT FACILITY ALONE. BY VIRTUE OF THE OVERLAP OF THE CONTOURS OF THE TRANSMITTERS, THEY ARE CONTIGUOUS, THEREBY MEETING THE REQUIREMENTS OF 73.626(F)(3). ALSO SHOWN IN FIGURE 2, IN BLUE, IS THE 48 DBU CONTOUR OF THE DTS SITE 1 FACILITY, WHICH CAN BE SEEN TO ENCOMPASS THE ENTIRE COUNTY OF LOS ANGELES, CA, IN WHICH IS LOCATED THE CITY OF LOS ANGELES, TO WHICH KNBC IS LICENSED. ALL FOUR TRANSMITTERS IN THE PROPOSED DTS NETWORK ARE LOCATED WITHIN THE KNBC ''LARGEST STATION'' ALTERNATIVE TO THE TABLE OF DISTANCES AREA (DISCUSSED IN DETAIL BELOW), CONSEQUENTLY MEETING THE REQUIREMENTS OF SECTION 73.626(F)(6).

THE CHARACTERISTICS OF THE DTS SITE 1 (MT WILSON) FACILITY ARE FULLY DESCRIBED IN FIGURE 1A. THE ANTENNA IS INSTALLED WITH 1 DEGREE OF MECHANICAL BEAM TILT DOWNWARD IN THE DIRECTION OF 215 DEGREES TRUE. THE ANTENNA HAS ELLIPTICAL POLARIZATION, WITH 16.67 PERCENT OF THE POWER APPLIED TO THE VERTICAL POLARIZATION COMPONENT. ELEVATION POWER GAIN OF THE ANTENNA IS 13.80 (11.38 DBD) IN THE HORIZONTAL POLARIZATION COMPONENT AND 2.80 (4.39 DBD) IN THE VERTICAL POLARIZATION COMPONENT AT THE VERTICAL BEAM MAXIMUM (1.0 DEGREE BELOW THE PLANE ORTHOGONAL TO THE AXIS OF THE ANTENNA AND THROUGH ITS RADIATION CENTER). AZIMUTH POWER GAIN OF THE ANTENNA IN THE HORIZONTAL POLARIZATION COMPONENT IS VIRTUALLY NIL (1.023 OR 0.10 DBD). THE MECHANICAL BEAM TILT CAUSES THE GAIN OF THE HORIZONTAL POLARIZATION COMPONENT TO VARY IN THE HORIZONTAL PLANE BETWEEN 13.80 (11.38 DBD) AT 35 DEGREES AZIMUTH AND 8.79 (9.44 DBD) AT 215 DEGREES AZIMUTH.

A PLOT OF THE AZIMUTHAL RADIATION PATTERN OF THE DTS SITE 1 ANTENNA IN RELATIVE FIELD VALUES OF THE HORIZONTAL POLARIZATION COMPONENT, PRIOR TO THE APPLICATION OF MECHANICAL BEAM TILT, (I.E., 1 DEGREE BELOW THE PLANE ORTHOGONAL TO THE AXIS OF THE ANTENNA AND THROUGH ITS RADIATION CENTER) IS INCLUDED AS FIGURE 3. THE AZIMUTHAL RADIATION PATTERN IN RELATIVE FIELD VALUES OF THE HORIZONTAL POLARIZATION COMPONENT IN THE HORIZONTAL PLANE, AFTER APPLICATION OF MECHANICAL BEAM TILT, IS INCLUDED AS FIGURE 4.   THE AZIMUTHAL POWER PATTERN OF THE HORIZONTAL POLARIZATION COMPONENT, EXPRESSED IN DECIBELS RELATIVE TO 1 KW (DBK), PRIOR TO THE APPLICATION OF MECHANICAL BEAM TILT, (I.E., 1 DEGREE BELOW THE PLANE ORTHOGONAL TO THE AXIS OF THE ANTENNA AND THROUGH ITS RADIATION CENTER) IS INCLUDED AS FIGURE 5. THE AZIMUTHAL POWER PATTERN OF THE HORIZONTAL POLARIZATION COMPONENT, EXPRESSED IN DECIBELS RELATIVE TO 1 KW (DBK) IN THE HORIZONTAL PLANE, IS PLOTTED IN FIGURE 6. TABULATED AZIMUTHAL FIELD AND POWER VALUES OF THE HORIZONTAL POLARIZATION COMPONENT DERIVED FROM THE DATA ARRAYS USED TO GENERATE FIGURES 3 THROUGH 6 ARE GIVEN IN FIGURE 7. THE ELEVATION RADIATION PATTERN IN RELATIVE FIELD VALUES OF THE HORIZONTAL POLARIZATION COMPONENT ALONG THE AXIS OF THE ANTENNA IS INCLUDED AS FIGURE 8. THE ELEVATION POWER PATTERN OF THE HORIZONTAL POLARIZATION COMPONENT, EXPRESSED IN DECIBELS RELATIVE TO 1 KW (DBK) ALONG THE AXIS OF THE ANTENNA, IS PLOTTED IN FIGURE 9. TABULATED ELEVATION FIELD AND POWER VALUES OF THE HORIZONTAL POLARIZATION COMPONENT DERIVED FROM THE DATA ARRAYS USED TO GENERATE FIGURES 8 &9 ARE GIVEN IN FIGURE 10.

BECAUSE OF THE MECHANICAL BEAM TILT APPLIED TO THE SITE 1 ANTENNA, ITS ELEVATION PATTERN VARIES WITH AZIMUTH, AND ITS AZIMUTH PATTERN VARIES WITH DEPRESSION ANGLE. THEREFORE, COMPLETE PATTERN DATA FOR THE ANTENNA FOR DTS SITE 1 IS BEING SUPPLIED THROUGH A COMPLEX ELEVATION PATTERN DATA FILE UPLOADED TO THE CDBS ELECTRONIC FILING SYSTEM. IN THAT FILE, DEPRESSION ANGLE VALUES ARE INCLUDED IN THE FIRST COLUMN, AND AZIMUTH VALUES ARE INCLUDED IN THE FIRST ROW. THE AZIMUTH AND ELEVATION PATTERN PLOTS AND TABULAR DATA SUPPLIED IN THIS TECHNICAL STATEMENT ARE FOR REFERENCE ONLY AND ARE INTENDED TO HELP IN VISUALIZATION OF THE CHARACTERISTICS OF THE ANTENNA. FULL SPECIFICATION OF THE ANTENNA PATTERN IS CONTAINED WHOLLY AND ONLY WITHIN THE ELEVATION PATTERN DATA FILE UPLOADED WITH THE FORM 301 APPLICATION.

IT SHOULD BE NOTED THAT, DUE TO LIMITATIONS IN THE FORM 301 DTS ENGINEERING PAGES IN THE CDBS ELECTRONIC FILING SYSTEM (EFS) AND BECAUSE THE VALUES IN THE AZIMUTH PATTERN RELATIVE FIELD DATA INPUT THERE ARE MULTIPLIED BY THE DATA IN THE ELEVATION PATTERN DATA FILE IN THE COMMISSIONS PROCESSING SOFTWARE, IT IS NOT POSSIBLE TO ENTER DATA INTO THE AZIMUTH PATTERN INPUT FIELDS THAT ARE REPRESENTATIVE OF THE HORIZONTAL PLANE PATTERN SUBSEQUENT TO INCLUSION OF THE EFFECTS OF MECHANICAL BEAM TILT. DOING SO WOULD RESULT IN DISTORTION OF THE ACTUAL PATTERN DATA AND LEAD TO INCORRECT ANALYSES OF THE PREDICTED INTERFERENCE FROM OR TO A STATION UNDER STUDY. MOREOVER, SINCE THE COMMISSIONS PROCESSING SOFTWARE DOES NOT HAVE THE ABILITY TO APPLY MECHANICAL BEAM TILT TO MORE THAN ONE ANTENNA IN A STUDY AND DOES NOT CURRENTLY APPLY MECHANICAL TILT IN A NON-DISTORTING WAY TO AN ANTENNA PATTERN, IT IS NECESSARY TO PUT DATA REPRESENTING THE RADIATION PATTERN OF EACH ANTENNA SUBSEQUENT TO APPLICATION OF MECHANICAL TILT INTO THE CORRESPONDING UPLOADED ELEVATION PATTERN DATA FILE, WHICH IS THE ONLY AVAILABLE MECHANISM THAT HAS SUFFICIENT DATA REPRESENTATION CAPACITY TO CARRY THE REQUIRED AMOUNT OF DATA. AS A RESULT OF ALL OF THIS, IT IS NECESSARY EITHER TO SET THE CHECK BOX RELATED TO THE AZIMUTH PATTERN INPUT FIELDS TO ''N/A'', WHICH PARENTHETICALLY ALSO INDICATES ''NON-DIRECTIONAL'', OR NOT TO CHECK THE ''N/A'' BOX BUT TO PUT VALUES OF 1.000 IN ALL OF THE AZIMUTH PATTERN DATA FIELDS. THE LATTER APPROACH AT LEAST INDICATES THAT THE ANTENNA IS DIRECTIONAL AND THEREFORE WAS TAKEN IN THE INSTANT APPLICATION FOR EACH OF THE DTS SITES AND THEIR ANTENNA PATTERNS.

THE PROPOSED DTS SITE 2 (TABLE MOUNTAIN) ANTENNA WILL HAVE COLUMNS OF PANELS FACING 62 AND 327 DEGREES TRUE, WITH RESULTING MAJOR AZIMUTH LOBES AT 15, 61, AND 328 DEGREES TRUE. IT WILL HAVE AN ELEVATION PATTERN WITH ITS MAIN LOBE 3 DEGREES BELOW THE PLANE ORTHOGONAL TO THE AXIS OF THE ANTENNA AND THROUGH ITS RADIATION CENTER. THE ELEVATION PATTERN ALSO WILL CONTAIN A NOTCH ABOVE THE MAIN LOBE AT 0.2 DEGREE ABOVE THE PLANE ORTHOGONAL TO THE AXIS OF THE ANTENNA AND THROUGH ITS RADIATION CENTER. MECHANICAL BEAM TILT OF 2.3 DEGREES DOWNWARD WILL BE APPLIED TO THE ANTENNA AT A BEARING OF 204 DEGREES TRUE. THIS WILL RESULT IN THE MAIN BEAM BEING LIFTED TO A DEPRESSION ANGLE OF 0.7 DEGREES TOWARD A BEARING OF 24 DEGREES TRUE AND BEING PUSHED DOWN TO A DEPRESSION ANGLE OF 5.3 DEGREES AT THE 204-DEGREE BEARING. IT ALSO WILL RESULT IN THE NOTCH ABOVE THE MAIN BEAM BEING PUSHED DOWN TO A DEPRESSION ANGLE OF 2.1 DEGREES AT THE 204-DEGREE BEARING.

THE CHARACTERISTICS AND PARAMETERS OF DTS SITE 2 ARE FULLY DESCRIBED IN FIGURE 1B. THE DTS SITE 2 ANTENNA WILL HAVE CIRCULAR POLARIZATION, WITH EQUAL POWER APPLIED TO BOTH THE HORIZONTAL AND VERTICAL POLARIZATION COMPONENTS; THUS THE EFFECTIVE RADIATED POWER OF EACH INDIVIDUAL COMPONENT IS BASED ON HALF THE POWER INPUT TO THE ANTENNA. ELEVATION POWER GAIN OF THE ANTENNA DESIGN FOR DTS SITE 2, AT THE AZIMUTH OF BEAM MAXIMUM (61 DEGREES) AND IN EACH OF THE HORIZONTAL AND VERTICAL POLARIZATION COMPONENTS, IS 12.90 (11.12 DBD) AT THE BEAM MAXIMUM (3.0 DEGREES BELOW THE PLANE ORTHOGONAL TO THE AXIS OF THE ANTENNA AND THROUGH ITS RADIATION CENTER) AND JUST OVER 0.0029 (25.36 DBD) AT THE NULL ABOVE THE MAIN BEAM (0.2 DEGREES ABOVE THE PLANE ORTHOGONAL TO THE AXIS OF THE ANTENNA AND THROUGH ITS RADIATION CENTER). THE AZIMUTH POWER GAIN, AT THE DEPRESSION ANGLE OF BEAM MAXIMUM (3.0 DEGREES BELOW THE PLANE ORTHOGONAL TO THE AXIS OF THE ANTENNA AND THROUGH ITS RADIATION CENTER) AND IN EACH OF THE HORIZONTAL AND VERTICAL POLARIZATION COMPONENTS IS 2.90 (4.62 DB). THE TOTAL POWER GAIN IN EACH OF THE HORIZONTAL AND VERTICAL POLARIZATION COMPONENTS IN THE MAIN BEAM IS 37.41 (15.73 DBD). THE MECHANICAL BEAM TILT CAUSES THE GAIN OF EACH OF THE HORIZONTAL AND VERTICAL POLARIZATION COMPONENTS TO VARY IN THE HORIZONTAL PLANE BETWEEN 23.61 (13.73 DBD) AT 53 DEGREES AZIMUTH AND 0.000002647 ( 55.77 DBD) AT 194 DEGREES AZIMUTH.

THE TABULATED ELEVATION FIELD AND POWER VALUES ARE GIVEN IN FIGURE 16.

BECAUSE OF THE MECHANICAL BEAM TILT APPLIED TO THE DTS SITE 2 ANTENNA, ITS ELEVATION PATTERN VARIES WITH AZIMUTH, AND ITS AZIMUTH PATTERN VARIES WITH DEPRESSION ANGLE.

THE PROPOSED DTS SITES 3 AND 4 ANTENNAS (BOTH OF WHICH WILL BE AT OAT MOUNTAIN) WILL BE COMPOSED OF SINGLE COLUMNS OF PANELS 6 FOR DTS SITE 3 AND 4 FOR DTS SITE 4. THERE WILL BE NO ELECTRICAL BEAM TILT APPLIED TO THE ELEVATION PATTERN OF EITHER ANTENNA; ONLY MECHANICAL BEAM TILT WILL BE APPLIED TO EACH OF THEM. THE DTS SITE 3 ANTENNA WILL BE ORIENTED WITH ITS MAIN BEAM TOWARD AN AZIMUTH OF 255 DEGREES TRUE AND 1.5 DEGREES BELOW THE HORIZONTAL AT THE SAME HEADING. THE DTS SITE 4 ANTENNA WILL BE MOUNTED 20 METERS BELOW THE DTS SITE 3 ANTENNA ON THE SAME TOWER. IT WILL BE ORIENTED WITH ITS MAIN BEAM TOWARD AN AZIMUTH OF 15 DEGREES AND 2.0 DEGREES BELOW THE HORIZONTAL AT THE SAME HEADING.

THE CHARACTERISTICS AND PARAMETERS OF DTS SITES 3 AND 4 ARE FULLY DESCRIBED IN FIGURES 1C AND 1D, RESPECTIVELY. THEIR ANTENNAS WILL HAVE CIRCULAR POLARIZATION, WITH EQUAL POWER APPLIED TO BOTH THE HORIZONTAL AND VERTICAL POLARIZATION COMPONENTS; THUS, THE EFFECTIVE RADIATED POWER OF EACH INDIVIDUAL COMPONENT IS BASED ON HALF THE POWER INPUT TO ITS RESPECTIVE ANTENNA. ELEVATION POWER GAIN OF THE ANTENNA DESIGN FOR DTS SITE 3, AT THE AZIMUTH OF BEAM MAXIMUM (255 DEGREES) AND IN EACH OF THE HORIZONTAL AND VERTICAL POLARIZATION COMPONENTS, IS 14.24 (11.54 DBD) AT THE BEAM MAXIMUM (IN THE PLANE ORTHOGONAL TO THE AXIS OF THE ANTENNA AND THROUGH ITS RADIATION CENTER). THE AZIMUTH POWER GAIN, AT THE DEPRESSION ANGLE OF BEAM MAXIMUM (IN THE PLANE ORTHOGONAL TO THE AXIS OF THE ANTENNA AND THROUGH ITS RADIATION CENTER) AND IN EACH OF THE HORIZONTAL AND VERTICAL POLARIZATION COMPONENTS IS 5.63 (7.51 DB). THE TOTAL POWER GAIN IN EACH OF THE HORIZONTAL AND VERTICAL POLARIZATION COMPONENTS IN THE MAIN BEAM IS 80.17 (19.04 DBD). THE MECHANICAL BEAM TILT CAUSES THE GAIN OF EACH OF THE HORIZONTAL AND VERTICAL POLARIZATION COMPONENTS TO VARY IN THE HORIZONTAL PLANE BETWEEN 53.80 (17.31 DBD) AT 255 DEGREES AZIMUTH AND 0.27878 ( 5.55 DBD) AT BOTH 43 AND 107 DEGREES AZIMUTH.

THE TABULATED AZIMUTHAL FIELD AND POWER VALUES FOR THE DTS SITES 3 & 4 ANTENNAS ARE GIVEN IN FIGURE 19. THE ELEVATION RADIATION PATTERNS IN RELATIVE FIELD VALUES ALONG THE AXES OF THE ANTENNAS, IN THE AZIMUTHAL DIRECTIONS HAVING MAXIMUM FIELD (255 AND 15 DEGREES FOR DTS SITES 3 & 4, RESPECTIVELY), ARE INCLUDED AS FIGURES 20A AND 20B. THE ELEVATION POWER PATTERNS EXPRESSED IN DECIBELS RELATIVE TO 1 KW (DBK) ALONG THE AXES OF THE ANTENNAS, IN THE AZIMUTHAL DIRECTIONS HAVING MAXIMUM POWER (ALSO 255 AND 15 DEGREES FOR DTS SITES 3 & 4, RESPECTIVELY), ARE PLOTTED IN FIGURES 21A AND 21B. THE TABULATED ELEVATION FIELD AND POWER VALUES ARE GIVEN IN FIGURE 22.

BECAUSE OF THE MECHANICAL BEAM TILT APPLIED TO THE DTS SITES 3 & 4 ANTENNAS, THEIR ELEVATION PATTERNS VARY WITH AZIMUTH, AND THEIR AZIMUTH PATTERNS VARY WITH DEPRESSION ANGLE. THEREFORE, COMPLETE PATTERN DATA FOR THE ANTENNAS FOR DTS SITES 3 & 4 ARE BEING SUPPLIED THROUGH COMPLEX ELEVATION PATTERN DATA FILES UPLOADED TO THE CDBS ELECTRONIC FILING SYSTEM. IN THOSE FILES, DEPRESSION ANGLE VALUES ARE INCLUDED IN THE FIRST COLUMNS, AND AZIMUTH VALUES ARE INCLUDED IN THE FIRST ROWS. THE AZIMUTH AND ELEVATION PATTERN PLOTS AND TABULAR DATA SUPPLIED IN THIS TECHNICAL STATEMENT ARE FOR REFERENCE ONLY AND ARE INTENDED TO HELP IN VISUALIZATION OF THE CHARACTERISTICS OF THE ANTENNAS. FULL SPECIFICATIONS OF THE ANTENNA PATTERNS ARE CONTAINED WHOLLY AND ONLY WITHIN THE ELEVATION PATTERN DATA FILES UPLOADED WITH THE FORM 301 APPLICATION. IT SHOULD BE NOTED THAT THE LIMITATIONS OF THE CDBS EFS FORM 301 DTS ENGINEERING WEB PAGES REGARDING INCLUSION OF AZIMUTH PATTERN RELATIVE FIELD VALUES AND THE RELATED CHECK BOXES, DESCRIBED ABOVE WITH RESPECT TO THE DTS SITE 1 ANTENNA, APPLY EQUALLY WITH RESPECT TO THE DTS SITES 3 & 4 ANTENNAS AND THAT THE SAME APPROACH TAKEN FOR SITE 1 HAS BEEN FOLLOWED FOR SITES 3 & 4.

ALL OF THE TRANSMITTERS TO BE USED IN THE KNBC DTS NETWORK WILL BE TYPE VERIFIED AS PER SECTION 73.1660 OF THE COMMISSIONS RULES. ALL TRANSMITTERS WILL BE SYNCHRONIZED, EMITTING IDENTICAL SYMBOLS ON PRECISELY THE SAME FREQUENCY; THEY WILL TRANSMIT THE RF WATERMARK TRANSMITTER IDENTIFICATION SIGNAL DEFINED IN THE ATSC A/110 TRANSMITTER SYNCHRONIZATION STANDARD.
