In 2007, free-to-air television broadcasters in Hong Kong were allocated extra frequency bands and bandwidth to provide additional digital broadcasts over and above that needed to provide simultaneous digital and analogue broadcasting of the four original multi frequency free-to-air channels. Digital terrestrial broadcasts began on 31 December ...
The upper antenna is a Yagi design. UHF television broadcasting is the use of ultra high frequency (UHF) radio for over-the-air transmission of television signals. UHF frequencies are used for both analog and digital television broadcasts. UHF channels are typically given higher channel numbers, like the US arrangement with VHF channels ...
Noise temperature (antenna) In radio frequency (RF) applications such as radio, radar and telecommunications, noise temperature of an antenna is a measure of the noise power density contributed by the antenna to the overall RF receiver system. It is defined as "the temperature of a resistor having an available thermal noise power per unit ...
Antenna gain-to-noise-temperature ( G/T) is a figure of merit in the characterization of antenna performance, where G is the antenna gain in decibels at the receive frequency, and T is the equivalent noise temperature of the receiving system in kelvins. The receiving system noise temperature is the summation of the antenna noise temperature and ...
The following is a list of programs that are and will be broadcast on Antenna TV, a general entertainment network owned by the Tribune Broadcasting subsidiary of the Tribune Company, which is designed for digital subchannels of over-the-air broadcast stations in the United States and was launched on January 1, 2011.

The VHF band is further divided into two frequency ranges: VHF low band ( Band I) between 54 and 88 MHz, containing channels 2 through 6, and VHF high band ( Band III) between 174 and 216 MHz, containing channels 7 through 13. The wide spacing between these frequency bands is responsible for the complicated design of rooftop TV antennas.
A television antenna, also called a television aerial (in British English ), is an antenna specifically designed for use with a television receiver (TV) to receive terrestrial over-the-air (OTA) broadcast television signals from a television station. Terrestrial television is broadcast on frequencies from about 47 to 250 MHz in the very high ...
This is a list of the current channels available on digital terrestrial television (DTT) in the United Kingdom, and those that have been removed.. Almost all channels broadcast on DTT are free-to-air, with a limited number of subscription channels (requiring a subscription to a pay-TV package) and pay-per-view channels (requiring a one-off payment to view an event) also available.
