  2. Antenna tuner - Wikipedia

    en.wikipedia.org/wiki/Antenna_tuner

    Transformers, autotransformers, and baluns are sometimes incorporated into the design of narrow band antenna tuners and antenna cabling connections. They will all usually have little effect on the resonant frequency of either the antenna or the narrow band transmitter circuits, but can widen the range of impedances that the antenna tuner can match, and/or convert between balanced and ...

  4. Tuner (radio) - Wikipedia

    en.wikipedia.org/wiki/Tuner_(radio)

    A television tuner or TV tuner, also called a TV receiver, is a component or subsystem that converts analog television or digital television transmissions into audio and video signals which can be further processed to produce sound and a picture. [29] [30] [31] A TV tuner must filter out unwanted signals and have a high signal-to-noise ratio. [32]

  7. Preselector - Wikipedia

    en.wikipedia.org/wiki/Preselector

    Although a preselector is placed inbetween the radio and the antenna, in the same electrical location as a feedline matching unit, it serves a different purpose: A transmatch or "antenna" tuner connects two transmission lines with different impedances and only incidentally blocks out-of-tune frequencies (if it blocks any at all).

  8. Low-noise block downconverter - Wikipedia

    en.wikipedia.org/wiki/Low-noise_block_downconverter

    This LNB has one port for all vertical polarised channels both low and high band, and another port for all low and high band horizontal channels. The basic model has only 2 connections and presumably has a local oscillator of 10.41 GHz with an intermediate frequency of 290–2340 MHz from an input of 10.7–12.75 GHz.

  9. Antenna tuning hut - Wikipedia

    en.wikipedia.org/wiki/Antenna_tuning_hut

    An antenna tuning hut or helix house is a small shed at the base of a longwave or mediumwave radio transmitting antenna. It contains antenna tuner — radio equipment for coupling the power from the feedline to the antenna. [1] Alternative names include antenna tuning house, coupling hut, and dog house.
