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 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 ...
In wireless communications, channel state information ( CSI) is the known channel properties of a communication link. This information describes how a signal propagates from the transmitter to the receiver and represents the combined effect of, for example, scattering, fading, and power decay with distance. The method is called channel estimation.
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.

T4 was a scheduling slot on Channel 4 ( T4 Saturday usually 9 am until 2 pm) and E4 ( T4 Sunday usually 9 am until 5 pm). It also aired on weekdays in the school holidays. The slot had a separate station identification on screen graphic from Channel 4 and E4. Channel 4 originally produced the strand in-house until 2002, when production was ...

Effective isotropic radiated power is the hypothetical power that would have to be radiated by an isotropic antenna to give the same ("equivalent") signal strength as the actual source antenna in the direction of the antenna's strongest beam. The difference between EIRP and ERP is that ERP compares the actual antenna to a half-wave dipole ...
