Summary

English: This thousand-foot tower, perhaps the tallest all-red object on Earth, is the landmark crown of TV Hill in Baltimore, and the transmitting home of the city's three alpha TV stations, plus two FMs, auxiliary backups for those FMs and two others in town, two translators for secondary HD channels of one FM and an FM translator for the city's biggest AM station.
The tower, known to the FCC as ASR (antenna structure registration) 1035558, was built in 1958-59 for the city's three network TV stations: WMAR/2 (ABC), WBAL-TV/11 (NBC) and WJZ-TV/13 (CBS). The tower was stretched upward by another 270 feet in 2004. Data on the tower: The tower base and cable anchors required 2,250 tons of concrete. Structure Coordinates: 39-20-5.0 N 76-39-2.0 W (NAD 83) Site Elevation: 97 meters (318 ft) Height of Structure: 271 meters (889 feet) Overall Height Above Ground: 304 meters (997 feet) Overall Height Above Mean Sea Level: 401 meters (1316 feet) Data on the TV stations: WJZ-TV Virtual channel 13 Actual channel 11 ERP: 35.5 kW Polarization: Horizontally polarized HAAT: 273 m (896 ft.) Electrical Beam Tilt: 2.0 degrees R/C AGL: 261 m (856 ft.) Directional Antenna, broad, but leaning northeast Antenna Make/Model: DIELECTRIC TLS-V4BB Antenna ID: 1007017 Horizontally polarized WMAR Virtual channel 2 Actual channel 27 ERP: 830 kW Polarization: Elliptically polarized HAAT: 307 m (1007 ft.) Electrical Beam Tilt: 0.75 degrees Omni-Directional Antenna - Antenna Make/Model: DIELECTRIC TFU-28GTH/VP-R-06 Antenna ID: 84898 WBAL-TV Virtual channel 11 Actual channel 12 ERP: 30 kW Polarization: Circularly polarized HAAT: 305 m (1001 ft.) Electrical Beam Tilt: 0.75 degrees Omni-Directional Antenna - Antenna Make/Model: DIELECTRIC THV-9A12/CP-R O4 Antenna ID: 1001245 All three station antennas are above the three corners of the candelabra. All three also have auxiliary antennas hanging down from the sides of the platform. On FM, the two full-power stations are WMMX/106.5 and WIYY/97.9. Both share the same two-bay panel antenna on the WMAR mast. Data: Effective Radiated Power: 10.5 kW Antenna Center HAAT: 296 m (971 ft.) Antenna Center AMSL: 379 m (1243 ft.) Antenna Center HAG: 282 m (925 ft.) Omni-Directional Antenna Antenna Make/Model: Electronics Research Inc. 1183-2CP Antenna ID: 1007578 Auxiliary antennas on the tower are for those two stations, plus WJZ/105.7 and WLIF/101.9. There are also translator antennas for WBAL-AM/1090 on 101.5, WLIF-HD2 on 106.1 and WLIF-HD4 on 97.5. Mouse over for details. |
