  2. Monopole antenna - Wikipedia

    en.wikipedia.org/wiki/Monopole_antenna

    A typical mast radiator monopole antenna of an AM radio station in Chapel Hill, North Carolina. The mast itself is connected to the transmitter and radiates the radio waves. It is mounted on a ceramic insulator to isolate it from the ground. The other terminal of the transmitter is connected to a ground system consisting of cables buried under ...

  3. Hexbeam - Wikipedia

    en.wikipedia.org/wiki/Hexbeam

    Radio amateurs can build the Hexbeam as a multi-band antenna to cover different frequency ranges. Popular combinations cover 20m, 15m and 10m (3 band) and 20m, 17m, 15m, 12m and 10m (5-band) ham radio bands. Hexbeams can also be built for the 40m and 30m bands. The antenna elements for the lowest frequency band are located at the exterior of ...

  4. Whip antenna - Wikipedia

    en.wikipedia.org/wiki/Whip_antenna

    Whip antenna on portable FM radio receiver Whip antenna on car. A whip antenna is an antenna consisting of a straight flexible wire or rod. The bottom end of the whip is connected to the radio receiver or transmitter. A whip antenna is a form of monopole antenna. The antenna is designed to be flexible so that it does not break easily, and the ...

  5. Antenna rotator - Wikipedia

    en.wikipedia.org/wiki/Antenna_rotator

    An antenna rotator (or antenna rotor) is a device used to change the orientation, within the horizontal plane, of a directional antenna. Most antenna rotators have two parts, the rotator unit and the controller. The controller is normally placed near the equipment which the antenna is connected to, while the rotator is mounted on the antenna ...

  6. Antenna types - Wikipedia

    en.wikipedia.org/wiki/Antenna_types

    A modified mast antenna, usually grounded at its base, augmented by one or several parallel wires called "skirt wires" that attach to the mast part-way up the antenna. The skirt wires can attach at any height between part-way up and the top of the mast. One or more of the skirt wires is fed with the signal, similar to a gamma match.

  7. Radio masts and towers - Wikipedia

    en.wikipedia.org/wiki/Radio_masts_and_towers

    A mast radiator or mast antenna is a radio tower or mast in which the whole structure is an antenna. Mast antennas are the transmitting antennas typical for long or medium wave broadcasting. Structurally, the only difference is that some mast radiators require the mast base to be insulated from the ground.

  8. Folded unipole antenna - Wikipedia

    en.wikipedia.org/wiki/Folded_unipole_antenna

    The folded unipole antenna was first devised for broadcast use by John H. Mullaney, an American radio broadcast pioneer, and consulting engineer. [2] It was designed to solve some difficult problems with existing medium wave (MW), frequency modulation (FM), and amplitude modulation (AM) broadcast antenna installations.

  9. G5RV antenna - Wikipedia

    en.wikipedia.org/wiki/G5RV_antenna

    A transmatch (antenna tuner) is not required to use this antenna near its nominal design frequency of 14 MHz, and judicious length adjustments can sometimes include one other frequency band. All other frequencies require a transmatch. [citation needed] There are many variants of the G5RV antenna. Two variations of the G5RV design, called ZS6BKW ...
