  2. Diplexer - Wikipedia

    en.wikipedia.org/wiki/Diplexer

    Older TV installations may use a solid dielectric RG-59 cable, and that cable may be inadequate. [1] RG-6 cable is typically used for satellite feed lines. In this application, there would be a diplexer on the roof that joins the satellite dish feed and the TV antenna together into a single coaxial cable.

  3. Television antenna - Wikipedia

    en.wikipedia.org/wiki/Television_antenna

    A short antenna pole next to a house Multiple Yagi TV aerials. Antennas are commonly placed on rooftops and sometimes in attics. Placing an antenna indoors significantly attenuates the level of the available signal. [19] [20] Directional antennas must be pointed at the transmitter they are receiving; in most cases great accuracy is not needed ...

  4. Duplexer - Wikipedia

    en.wikipedia.org/wiki/Duplexer

    When the transmitter is active, the resulting high voltage causes the tube to conduct, shorting together the receiver terminals to protect it, while its complementary, the anti-transmit/receive (ATR) switch, is a similar discharge tube which decouples the transmitter from the antenna while not operating, to prevent it from wasting received energy.

  5. UHF television broadcasting - Wikipedia

    en.wikipedia.org/wiki/UHF_television_broadcasting

    This mast has two UHF antennas for receiving signals from different directions. The lower antenna is a bowtie array. 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 ...

  6. Antenna array - Wikipedia

    en.wikipedia.org/wiki/Antenna_array

    An antenna array (or array antenna) is a set of multiple connected antennas which work together as a single antenna, to transmit or receive radio waves. [1]: p.149 [2] The individual antennas (called elements) are usually connected to a single receiver or transmitter by feedlines that feed the power to the elements in a specific phase relationship.

  7. Antenna feed - Wikipedia

    en.wikipedia.org/wiki/Antenna_feed

    To connect balanced and unbalanced components, a two port device called a balun is used. A balun is a transformer that couples between balanced and unbalanced transmission line components. For example, to feed a dipole antenna from an unbalanced feedline like coaxial cable, the feedline is connected to the antenna through a balun. Without the ...

  9. Antenna diversity - Wikipedia

    en.wikipedia.org/wiki/Antenna_diversity

    Mobile phone towers also often take advantage of diversity - each face (sector) of a tower will often have two antennas; one is transmitting and receiving, while the other is a receive only antenna. Two receivers are used to perform diversity reception. Cell antennas on an electricity pylon showing two antennas per sector. The use of multiple ...
