  2. Twin-lead - Wikipedia

    en.wikipedia.org/wiki/Twin-lead

    For this reason, when attaching a twin-lead line to a coaxial cable connection, such as the 300 Ω twin-lead from a domestic television antenna to the television's 75 ohm coax antenna input, a balun with a 4:1 ratio is commonly used. Its purpose is double: First, it transforms twin-lead's 300 Ω impedance to match the 75 Ω coaxial cable ...

  3. Diplexer - Wikipedia

    en.wikipedia.org/wiki/Diplexer

    A diplexer allows two different devices to share a common communications channel. Typically, the channel is a long coaxial cable, and a diplexer is often used at both ends of the coaxial cable. The plan is feasible if the two devices operate on different frequencies. The plan is economical if the diplexers cost less than running a second cable.

  4. Coaxial cable - Wikipedia

    en.wikipedia.org/wiki/Coaxial_cable

    Coaxial cable, or coax (pronounced / ˈkoʊ.æks /), is a type of electrical cable consisting of an inner conductor surrounded by a concentric conducting shield, with the two separated by a dielectric (insulating material); many coaxial cables also have a protective outer sheath or jacket. The term coaxial refers to the inner conductor and the ...

  5. Transmission medium - Wikipedia

    en.wikipedia.org/wiki/Transmission_medium

    Coaxial cable is a type of transmission line, used to carry high frequency electrical signals with low losses. It is used in such applications as telephone trunk lines, broadband internet networking cables, high-speed computer data busses, carrying cable television signals, and connecting radio transmitters and receivers to their antennas.

  6. F connector - Wikipedia

    en.wikipedia.org/wiki/F_connector

    The F connector (also F-type connector) is a coaxial RF connector commonly used for "over the air" terrestrial television, cable television and universally for satellite television and cable modems, usually with RG-6/U cable or with RG-59/U cable. The F connector was invented by Eric E. Winston in the early 1950s while working for Jerrold ...

  7. Antenna types - Wikipedia

    en.wikipedia.org/wiki/Antenna_types

    Quarter-wave whip antenna on an FM radio for 88–108 MHz. Rubber ducky antenna on 446 MHz UHF walkie-talkie with rubber cover removed. VHF ground plane antenna. Mast radiator antenna of medium wave AM radio station, Germany. 'T' antenna of amateur radio station, 80 ft high, used at 1.5 MHz.

  8. Single-cable distribution - Wikipedia

    en.wikipedia.org/wiki/Single-cable_distribution

    Single-cable distribution is a satellite TV technology that enables the delivery of broadcast programming to multiple users over a single coaxial cable, and eliminates the numerous cables required to support consumer electronics devices such as twin- tuner digital video recorders (DVRs) and high-end receivers. Without single-cable distribution ...

  9. Substrate-integrated waveguide - Wikipedia

    en.wikipedia.org/wiki/Substrate-integrated_waveguide

    Substrate-integrated waveguide. The propagating electromagnetic waves are confined within the substrate by the metallic layers on each of the two faces of the substrate and between two rows of metallic vias connecting them. A substrate-integrated waveguide (SIW) (also known as post-wall waveguide or laminated waveguide) is a synthetic ...
