  2. Antenna gain-to-noise-temperature - Wikipedia

    en.wikipedia.org/wiki/Antenna_gain-to-noise...

    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 ...

  3. Noise temperature (antenna) - Wikipedia

    en.wikipedia.org/wiki/Noise_temperature_(antenna)

    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 ...

  4. Noise temperature - Wikipedia

    en.wikipedia.org/wiki/Noise_temperature

    The antenna noise temperature gives the noise power seen at the output of the antenna. The composite noise temperature of the receiver and transmission line losses represents the noise contribution of the rest of the receiver system. It is calculated as the effective noise that would be present at the antenna input terminals if the receiver ...

  5. Television antenna - Wikipedia

    en.wikipedia.org/wiki/Television_antenna

    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 ...

  6. Signal strength in telecommunications - Wikipedia

    en.wikipedia.org/wiki/Signal_strength_in...

    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).

  7. DVB-T2 - Wikipedia

    en.wikipedia.org/wiki/DVB-T2

    Ku band. Ka band. v. t. e. DVB-T2 is an abbreviation for " Digital Video Broadcasting – Second Generation Terrestrial "; it is the extension of the television standard DVB-T, issued by the consortium DVB, devised for the broadcast transmission of digital terrestrial television. DVB has been standardized by ETSI .

  8. Tower Mounted Amplifier - Wikipedia

    en.wikipedia.org/wiki/Tower_Mounted_Amplifier

    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 ...

  9. Very high frequency - Wikipedia

    en.wikipedia.org/wiki/Very_high_frequency

    VI. v. t. e. Very high frequency ( VHF) is the ITU designation [1] for the range of radio frequency electromagnetic waves ( radio waves) from 30 to 300 megahertz (MHz), with corresponding wavelengths of ten meters to one meter. Frequencies immediately below VHF are denoted high frequency (HF), and the next higher frequencies are known as ultra ...
