  3. Antenna amplifier - Wikipedia

    en.wikipedia.org/wiki/Antenna_amplifier

    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 ...

  4. Cellular repeater - Wikipedia

    en.wikipedia.org/wiki/Cellular_repeater

    A cellular repeater (also known as cell phone signal booster or cell phone signal amplifier) is a type of bi-directional amplifier used to improve cell phone reception. [citation needed] A cellular repeater system commonly consists of a donor antenna that receives and transmits signal from nearby cell towers, coaxial cables, a signal amplifier, and an indoor rebroadcast antenna.

  5. 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 ...

  6. 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 ...

  7. Noise figure - Wikipedia

    en.wikipedia.org/wiki/Noise_figure

    Noise figure. Noise figure (NF) and noise factor ( F) are figures of merit that indicate degradation of the signal-to-noise ratio (SNR) that is caused by components in a signal chain. These figures of merit are used to evaluate the performance of an amplifier or a radio receiver, with lower values indicating better performance.

  8. 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 ...

  9. Low-noise block downconverter - Wikipedia

    en.wikipedia.org/wiki/Low-noise_block_downconverter

    A low-noise block downconverter ( LNB) is the receiving device mounted on satellite dishes used for satellite TV reception, which collects the radio waves from the dish and converts them to a signal which is sent through a cable to the receiver inside the building. Also called a low-noise block, [ 1][ 2] low-noise converter ( LNC ), or even low ...
