  2. Antenna tuner - Wikipedia

    en.wikipedia.org/wiki/Antenna_tuner

    An antenna tuner, a matchbox, transmatch, antenna tuning unit (ATU), antenna coupler, or feedline coupler is a device connected between a radio transmitter or receiver and its antenna to improve power transfer between them by matching the impedance of the radio to the antenna's feedline. Antenna tuners are particularly important for use with ...

  3. Antenna (radio) - Wikipedia

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

    Antenna tuning, in the strict sense of modifying the antenna itself, generally refers only to cancellation of any reactance seen at the antenna terminals, leaving only a resistive impedance which might or might not be exactly the desired impedance (that of the available transmission line).

  4. 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.

  6. Variable capacitor - Wikipedia

    en.wikipedia.org/wiki/Variable_capacitor

    Variable capacitors are often used in L/C circuits to set the resonance frequency, e.g. to tune a radio (therefore it is sometimes called a tuning capacitor or tuning condenser), or as a variable reactance, e.g. for impedance matching in antenna tuners.

    en.wikipedia.org/wiki/Antenna_analyzer

    An antenna analyzer measuring SWR and complex impedance of a dummy load. MFJ-269, MFJ Enterprises Inc. An antenna analyzer or in British aerial analyser (also known as a noise bridge, RX bridge, SWR analyzer, or RF analyzer) is a device used for measuring the input impedance of antenna systems in radio electronics applications.

  8. Tuner (radio) - Wikipedia

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

    Marantz 2050L AM/FM stereo tuner (USA; 1978-1980) [1]. In electronics and radio, a tuner is a type of receiver subsystem that receives RF transmissions, such as AM or FM broadcasts, and converts the selected carrier frequency into a form suitable for further processing or output, such as to an amplifier or loudspeaker.
