    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.

  4. 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 ...

  6. Standing wave ratio - Wikipedia

    en.wikipedia.org/wiki/Standing_wave_ratio

    SWR of a vertical HB9XBG Antenna for the 40m-band as a function of frequency. In radio engineering and telecommunications, standing wave ratio (SWR) is a measure of impedance matching of loads to the characteristic impedance of a transmission line or waveguide.

  7. SWR meter - Wikipedia

    en.wikipedia.org/wiki/SWR_meter

    An SWR meter does not measure the actual impedance of a load (the resistance and reactance), but only the mismatch ratio. To measure the actual impedance requires an antenna analyzer or other similar RF measuring device. For accurate readings, the SWR meter itself must also match the line's impedance (typically 50 or 75 Ohms).

  8. Preselector - Wikipedia

    en.wikipedia.org/wiki/Preselector

    A preselector is a name for an electronic device that connects between a radio antenna and a radio receiver. The preselector is a band-pass filter that blocks troublesome out-of-tune frequencies from passing through from the antenna into the radio receiver (or preamplifier) that otherwise would be directly connected to the antenna.

  9. Amateur radio propagation beacon - Wikipedia

    en.wikipedia.org/wiki/Amateur_radio_propagation...

    An amateur radio propagation beacon is a radio beacon, whose purpose is the investigation of the propagation of radio signals. Most radio propagation beacons use amateur radio frequencies. They can be found on LF, MF, HF, VHF, UHF, and microwave frequencies. Microwave beacons are also used as signal sources to test and calibrate antennas and ...
