説明 | 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-TVVirtual channel 13Actual channel 11ERP: 35.5 kWPolarization: Horizontally polarizedHAAT: 273 m (896 ft.)Electrical Beam Tilt: 2.0 degreesR/C AGL: 261 m (856 ft.)Directional Antenna, broad, but leaning northeastAntenna Make/Model: DIELECTRIC TLS-V4BBAntenna ID: 1007017Horizontally polarizedWMARVirtual channel 2Actual channel 27ERP: 830 kWPolarization: Elliptically polarizedHAAT: 307 m (1007 ft.)Electrical Beam Tilt: 0.75 degreesOmni-Directional Antenna - Antenna Make/Model: DIELECTRIC TFU-28GTH/VP-R-06Antenna ID: 84898WBAL-TVVirtual channel 11Actual channel 12ERP: 30 kWPolarization: Circularly polarizedHAAT: 305 m (1001 ft.)Electrical Beam Tilt: 0.75 degreesOmni-Directional Antenna - Antenna Make/Model: DIELECTRIC THV-9A12/CP-R O4Antenna ID: 1001245All 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.
