| 説明 | Antenna Structure Number 1064388, home of KALW/91.7, the public radio voice of the San Francisco Unified School District, standing on Twin Peaks, the best place to drive up and have a look at the City if the fog's not blowing.Details:Site Location: 37-45-17.0 N 122-26-44.0 W (NAD 27)Effective Radiated Power: 1.9 kW Transmitter Output Power: 2.18 kW Antenna Center HAAT: 280 m (919 ft.)Antenna Center AMSL: 310 m (1017 ft.)Antenna Center HAG: 51 m (167 ft.)Site Elevation: 259 m. (850 ft.)Height Overall*: 60 m (197 ft.)Omni-Directional Antenna Antenna Make/Model: Jampro JMPC-2, 2 sections, 1 wavelength spacedStructure Registration Number (ASN) 1064388I've always thought that KALW got out unusually well, in spite of its relatively low power, and subordinate geographical position relative to the Sutro Tower nearby. For example, it sounded better, at least to me, going down the coast around Pacifica and Half Moon Bay, than did the much closer and more elevated KQED/88.5, with 110kw ERP. |
