Sutro Tower
Sutro Tower is a unique three-legged tall TV and radio lattice tower located in San Francisco, California. Rising from a hill between Twin Peaks and Mount Sutro near Clarendon Heights, it is a prominent feature of the city skyline and a landmark for city residents and visitors. The tower was the tallest structure in San Francisco from the time of its completion in 1973 until it was surpassed by the Salesforce Tower in 2017. The tower is named after the family of Adolph Sutro, a businessman and former mayor of San Francisco. His grandson, Adolph Gilbert Sutro, built a mansion, ''La Avanzada'', on their property in the highest peaks of San Francisco. In 1948, the mansion and property was sold to the American Broadcasting Company, where it became the original home of their San Francisco operation as KGO Television. KGO then formed a consortium with KTVU, KRON, and KPIX, the three other major San Francisco television broadcasters at the time, to build and maintain the tower. It st ...

Radio Masts
Radio masts and towers are typically tall structures designed to support antennas for telecommunications and broadcasting, including television. There are two main types: guyed and self-supporting structures. They are among the tallest human-made structures. Masts are often named after the broadcasting organizations that originally built them or currently use them. In the case of a mast radiator or radiating tower, the whole mast or tower is itself the transmitting antenna. Terminology The terms "mast" and "tower" are often used interchangeably. However, in structural engineering terms, a tower is a self-supporting or cantilevered structure, while a mast is held up by stays or guys. Broadcast engineers in the UK use the same terminology. A mast is a ground-based or rooftop structure that supports antennas at a height where they can satisfactorily send or receive radio waves. Typical masts are of steel lattice or tubular steel construction. Masts themselves play no part in t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
San Bruno Mountain
San Bruno Mountain is horst fault block mountain located in northern San Mateo County, California; with some northern slopes crossing over into southern San Francisco, it is also surrounded by San Francisco Bay and the cities of Brisbane, Colma, Daly City, and South San Francisco. It is topped by a four mile long ridge. Trails along the summit afford expansive views of the San Francisco Bay Area. Radio Peak (elevation ) is the highest point, with several radio/TV broadcast towers, serving an area that would otherwise have poor service in the hilly Bay Area region. Much of the mountain lies within the San Bruno Mountain State Park. Next to the state park is the state San Bruno Mountain Ecological Reserve on the north slope. The distinct geology and weather of San Bruno Mountain set it apart from many other California coastal areas. The mountain provides habitat for several species of rare and endangered plants (see below) and butterflies; the '' Callippe silverspot'', ''Mis ...

FM Broadcasting
FM broadcasting is a method of radio broadcasting using frequency modulation (FM). Invented in 1933 by American engineer Edwin Armstrong, wide-band FM is used worldwide to provide high fidelity sound over broadcast radio. FM broadcasting is capable of higher fidelity—that is, more accurate reproduction of the original program sound—than other broadcasting technologies, such as AM broadcasting. It is also less susceptible to common forms of interference, reducing static and popping sounds often heard on AM. Therefore, FM is used for most broadcasts of music or general audio (in the audio spectrum). FM radio stations use the very high frequency range of radio frequencies. Broadcast bands Throughout the world, the FM broadcast band falls within the VHF part of the radio spectrum. Usually 87.5 to 108.0 MHz is used, or some portion thereof, with few exceptions: * In the former Soviet republics, and some former Eastern Bloc countries, the older 65.8–74 MHz band ...

2016 United States Wireless Spectrum Auction
The 2016 United States wireless spectrum auction, officially known as Auction 1001, allocated approximately 100 MHz of the United States Ultra High Frequency (UHF) spectrum formerly allocated to UHF television in the 600 MHz band. The spectrum auction and subsequent reallocations were authorized by Title VI (The Spectrum Act) of the payroll tax cut extension passed by the United States Congress on February 17, 2012. Background The 2008 United States wireless spectrum auction, dealing with allocations for UHF television in the 700 MHz band, generated $19.6 billion from companies such as AT&T and Verizon Communications. This auction re-allocated the UHF space formerly occupied by channels 52–69, after the completion of the primary digital television transition in the United States from NTSC to ATSC in 2009. In effect, the digital transition had eliminated 25% of the space allocated for UHF television in the United States. Wireless broadband internet access interest ...
