  2. Moxon antenna - Wikipedia

    en.wikipedia.org/wiki/Moxon_antenna

    Moxon antenna for the 20-meter band.The antenna is the faint rectangle of wires held in tension by the bent X-shaped support frame. Moxon antenna for the 2-meter band. The Moxon antenna or Moxon rectangle is a simple and mechanically rugged two-element parasitic array, single-frequency antenna. [1]

  3. Quad antenna - Wikipedia

    en.wikipedia.org/wiki/Quad_antenna

    "A two-element, three-band quad, with elements mounted only 35 feet above ground, will give good performance in situations where a triband Yagi will not." [12] Shorter boom Orr (1996) [13] shows a 10, 15, and 20 meter, 2 element quad with boom length of 6′10″. Internally stackable

  4. Driven and parasitic elements - Wikipedia

    en.wikipedia.org/wiki/Driven_and_parasitic_elements

    Yagi antenna for UHF TV reception with 22 parasitic elements; 4 reflectors attached to the vertical bracket at left, and 18 directors attached to the horizontal beam at right. The driven element is attached to the black box next to the reflectors. The antenna is most sensitive to radio waves coming from the right, parallel to the antenna's axis.

  5. Television antenna - Wikipedia

    en.wikipedia.org/wiki/Television_antenna

    Outdoor antennas provide up to a 15 dB gain in signal strength and 15-20 dB greater rejection of ghost signals in analog TV. [6] Combined with a signal increase of 14 dB due to height and 11 dB due to lack of attenuating building walls, an outdoor antenna can result in a signal strength increase of up to 40 dB at the TV receiver.

  6. Log-periodic antenna - Wikipedia

    en.wikipedia.org/wiki/Log-periodic_antenna

    The Yagi and the LPDA designs look very similar at first glance, as they both consist of a number of dipole elements mounted along a support boom. The Yagi, however, has only a single driven element connected to the transmission line, usually the second one from the back of the array, the remaining elements are parasitic. The Yagi antenna ...

  7. Antenna types - Wikipedia

    en.wikipedia.org/wiki/Antenna_types

    Assuming the building is about 20 feet tall, the length of wire seems to be on the order of 100 feet long – too short to be an HF Beverage antenna. Random wire antenna Moxon (1993) describes the random-wire antenna as an "odd bit of wire". [14] [page needed] It is the typical informal antenna erected for receiving shortwave and AM radio.

  8. Loop antenna - Wikipedia

    en.wikipedia.org/wiki/Loop_antenna

    A ferrite loopstick antenna, a small loop used for AM reception in a portable radio, consisting of a wire wound around a ferrite core; the most common type of loop antenna today. A loop antenna is a radio antenna consisting of a loop or coil of wire, tubing, or other electrical conductor , that for transmitting is usually fed by a balanced ...

  9. 20-meter band - Wikipedia

    en.wikipedia.org/wiki/20-meter_band

    The 20-meter or 14-MHz amateur radio band is a portion of the shortwave radio spectrum, comprising frequencies stretching from 14.000 MHz to 14.350 MHz. [1] The 20-meter band is widely considered among the best for long-distance communication ( DXing ), and is one of the most popular—and crowded—during contests . [ 2 ]
