KSAN Transmitter Tower
Western Merchandise Mart
Sherwood Patterson bought KGGC from the Golden Gate Church in 1939. He moved the studios to the Western Merchandise Mart building at 1355 Market Street (between Ninth and Tenth streets) and built this tower on the roof of the building.
The tower was used for decades by the station, which later became KSOL and then KEST. The radiation performance of the antenna at 1450 kilocycles on the AM dial was poor, however, due to its short length and height above the ground.
The building, which has undergone extensive renovation over the years, is still in use as a wholesale home furnishings center as the San Francisco Mart (SFM).
