UHF channels are typically given higher channel numbers, like the US arrangement with VHF channels (initially) 1 to 13, and UHF channels (initially) numbered 14 to 83. Compared with an equivalent VHF television transmitter, to cover the same geographic area with a UHF transmitter requires a higher effective radiated power , implying a more ...
The IEEE defines the UHF radar band as frequencies between 300 MHz and 1 GHz. [1] Two other IEEE radar bands overlap the ITU UHF band: the L band between 1 and 2 GHz and the S band between 2 and 4 GHz. UHF television antenna on a residence. This type of antenna, called a Yagi–Uda antenna, is widely used at UHF frequencies.
The frequencies used by UHF channels 70 through 83 were reallocated to the Land Mobile Radio System (Public Safety and Trunked Radio) and mobile phones in a CCIR worldwide convention in 1982, and thus were never used for digital TV but are highlighted in cyan and listed here for theoretical use.
According to the FCC, as of March 31, 2011, there are 1022 UHF commercial television stations, 360 VHF commercial television stations, 285 UHF educational television stations and 107 VHF educational television stations, plus 439 Class A UHF television stations, 76 Class A VHF television stations, 3043 UHF television translators, 1411 VHF television translators, 1656 UHF low-power television ...
The Pan-American television frequencies are different for terrestrial and cable television systems. Terrestrial television channels are divided into two bands: the VHF band which comprises channels 2 through 13 and occupies frequencies between 54 and 216 MHz, and the UHF band, which comprises channels 14 through 36 and occupies frequencies between 470 and 608 MHz.
Until 1952, the FCC had allocated only 6 television channels to the Bay Area, but in 1954 KSAN [2] began transmitting on UHF channel 32 and KQED began educational programming on channel 9. By 1956, the Sacramento area had KCRA , KBET KOVR , and KCCC on the air, the San Jose area had KSBW and KNTV , and San Francisco had KRON , KPIX , KGO , KQED ...
While some Channel 5 stations were moved to 5A in the 1970s and 80s, beginning in the 1990s, the Australian Broadcasting Authority began a process to move these stations to UHF bands to free up valuable VHF spectrum for its original purpose of FM radio. In addition, by 1985 the federal government decided new TV stations are to be broadcast on ...
In the UK, Band IV allocations are 8 MHz wide, traditionally consisting of 14 channels from UHF 21 to 34 inclusive.However, in the mid-1990s the squeezing of analogue Channel 5 broadcasts into the existing national terrestrial TV transmitter network effectively closed a gap between bands IV and V, which was previously reserved for radar applications and home consumer devices.
