The Sutro Tower as viewed from the east

Sutro Tower is a three-pronged antenna tower on Mount Sutro in the western part of San Francisco, California at 37°45'19.0" N and 122°27'10.0" W. It is a dominant part of the city skyline, but is relatively unknown to tourists as it is often airbrushed out of travel brochures. It is less picturesque than other landmarks and is considerably west of the main downtown tourist area.

Reasons for the tower

Before its construction, television reception in San Francisco was quite spotty as the many hills of the city would block the line-of-sight radio waves - this was before the rise in popularity of cable television but is the main source of free over the air television in the Bay Area. Before Sutro Tower, transmitters were scattered throughout the Bay Area including at San Bruno Mountain, Mt. Allison, Monument Peak, and Mt. Diablo. Reception outside of San Francisco was incrementally improved by the tower. By having all the main Bay Area television stations in one location reception was improved by allowing all receiving antennas to be pointed at one tower instead of many. However, local NBC affiliate KNTV, which originally broadcast from Loma Prieta Peak in Santa Clara County, currently broadcasts from San Bruno Mountain. Most residents in San Mateo County, the East Bay, and Marin County can aim their antennas in the general direction on Sutro Tower and get all stations, including KNTV. Some residents in San Francisco need to rotate their antenna as San Bruno Mountain is approximately five miles south of Sutro Tower. Mount Diablo State Park is a state park in California, USA.

Construction

Construction began in 1971, by Kline Tower of Columbia, SC, and was completed in 1972, with the first transmissions from Sutro Tower on July 4, 1973. About 15 million pounds (6,800 tonnes) of concrete were used to make the foundation of the 3.7 million pound (1,700 tonne) tower. Earthquake proofing includes ballasting two thirds of the weight of the structure below ground, with resulting center of gravity at sixteen feet below ground level. It is used to transmit ten analog, eleven digital TV stations and four FM radio stations to the San Francisco Bay area. The tower is owned by Sutro Tower, Inc., which in turn is owned by four television stations KTVU, KRON, KPIX and KGO-TV with usage leased to other Bay Area TV and radio stations.
