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 ...
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 ...
Tower Mounted Amplifier. A Tower Mounted Amplifier ( TMA ), or Mast Head Amplifier ( MHA ), is a low-noise amplifier (LNA) mounted as close as practical to the antenna in mobile masts or base transceiver stations. A TMA reduces the base transceiver station noise figure (NF) and therefore improves its overall sensitivity; in other words the ...
Antenna amplifier for broadcasting service (here: TV broadcasting and FM souns broadcasting. In electronics, an antenna amplifier (also: aerial amplifier or booster) is a device that amplifies an antenna signal, usually into an output with the same impedance as the input impedance. Typically 75 ohm for coaxial cable and 300 ohm for twin-lead ...
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.

In telecommunications, [ 1] particularly in radio frequency engineering, signal strength refers to the transmitter power output as received by a reference antenna at a distance from the transmitting antenna. High-powered transmissions, such as those used in broadcasting, are expressed in dB - millivolts per metre (dBmV/m).
Pretty much everywhere in the U.S., the hottest part of the day is between 10 a.m. and 6 p.m. The body will gain heat from both the air temperature and solar radiation. The ground also heats up ...
Comparison of EM simulation software. The following table lists software packages with their own article on Wikipedia that are nominal EM (electromagnetic) simulators; Antenna modeling, especially in Amateur Radio. Widely used as the basis for many GUI-based programs on many platforms. Version 2 is open source, but Versions 3 and 4 are ...
