  2. Power dividers and directional couplers - Wikipedia

    en.wikipedia.org/wiki/Power_dividers_and...

    Directional couplers and power dividers have many applications. These include providing a signal sample for measurement or monitoring, feedback, combining feeds to and from antennas, antenna beam forming, providing taps for cable distributed systems such as cable TV, and separating transmitted and received signals on telephone lines.

  3. Wilkinson power divider - Wikipedia

    en.wikipedia.org/wiki/Wilkinson_power_divider

    No loss occurs when the signals at ports 2 and 3 are in phase and have equal magnitude. In case of noise input to ports 2 and 3, the noise level at port 1 does not increase, half of the noise power is dissipated in the resistor. By cascading, the input power might be divided to any -number of outputs.

  4. Belling-Lee connector - Wikipedia

    en.wikipedia.org/wiki/Belling-Lee_connector

    Female Belling-Lee connector on a television set. The Belling-Lee connector (also type 9,52, but largely only in the context of its specification, IEC 61169, Part 2: Radio-frequency coaxial connector of type 9,52) [1] is commonly used in Europe, parts of Southeast Asia, and Australia, to connect coaxial cables with each other and with terrestrial VHF/UHF roof antennas, antenna signal ...

  5. Antenna amplifier - Wikipedia

    en.wikipedia.org/wiki/Antenna_amplifier

    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 cable. An antenna amplifier boosts a radio signal considerably for devices that receive radio ...

  6. Antenna tuner - Wikipedia

    en.wikipedia.org/wiki/Antenna_tuner

    An antenna's impedance is different at different frequencies. An antenna tuner matches a radio with a fixed impedance (typically 50 Ohms for modern transceivers) to the combination of the feedline and the antenna; useful when the impedance seen at the input end of the feedline is unknown, complex, or otherwise different from the transceiver.

  7. TV aerial plug - Wikipedia

    en.wikipedia.org/wiki/TV_aerial_plug

    Belling-Lee connectors Flex Type F connectors. A TV aerial plug is a connector used to connect coaxial cables with each other and with terrestrial VHF/UHF roof antennas, antenna signal amplifiers, CATV distribution equipment, TV sets and FM / DAB-radio receivers.

  8. Fiber-optic splitter - Wikipedia

    en.wikipedia.org/wiki/Fiber-optic_splitter

    The FBT splitter uses two (or more) fibers. The fibers' coating layer is removed. Both fibers, at the same time, are stretched under a heating zone thus forming a double cone. This special waveguide structure allows control of the splitting ratio via controlling length of the fiber torsion angle and stretch.

  9. Digital television adapter - Wikipedia

    en.wikipedia.org/wiki/Digital_television_adapter

    The input digital signal may be over-the-air terrestrial television signals received by a television antenna, or signals from a digital cable system. It normally does not refer to satellite TV , which has always required a set-top box either to operate the big satellite dish , or to be the integrated receiver/decoder (IRD) in the case of direct ...
