  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]

    en.wikipedia.org/wiki/Clansman_(military_radio)

    The set operates in the 2–29.9999 MHz range with a possible 280,000 channels. [2] RF power output is a selectable 3 or 30 watts. [ 2 ] Derived from an earlier prototype known as the B20, [ 3 ] the PRC 320 can be used as a manpack (backpack) or vehicular radio and replaced the Larkspur Station Radio (SR) A13 SR C13 and other HF radios in ...

    en.wikipedia.org/wiki/List_of_amateur_radio...

    As an "all-band" transceiver, the TS-2000 offers a maximum power output of 100 watts on the HF, 6 meters, and 2 meters bands, 50 watts on 70 centimeters, and, with the TS-2000X or the optional UT-20, 10 watts on the 1.2 GHz or 23 centimeters band. The (American version) radio's main receiver covers 30 kHz through 60 MHz, 142 MHz through 152 MHz ...

  5. Directional antenna - Wikipedia

    en.wikipedia.org/wiki/Directional_antenna

    Patch antenna gain pattern. A directional antenna or beam antenna is an antenna which radiates or receives greater radio wave power in specific directions. Directional antennas can radiate radio waves in beams, when greater concentration of radiation in a certain direction is desired, or in receiving antennas receive radio waves from one specific direction only.

  6. WSPR (amateur radio software) - Wikipedia

    en.wikipedia.org/wiki/WSPR_(amateur_radio_software)

    The software code is now open source and is developed by a small team. The program is designed for sending and receiving low-power transmissions to test propagation paths on the MF and HF bands. WSPR implements a protocol designed for probing potential propagation paths with low-power transmissions.

    DIN 1.0/2.3 (DIN 47297), used for miniaturized 50 and 75 Ω coaxial modules in data- and telecommunications equipment which can have a threaded, or a push-pull lock coupling mechanism. DIN 1.6/5.6 (DIN 47295), a 75 Ω connector, used for similar purposes as DIN 1.0/2.3; FME connector; G-type connector; HD-BNC connector

  8. High frequency - Wikipedia

    en.wikipedia.org/wiki/High_frequency

    High frequency (HF) is the ITU designation [1] for the band of radio waves with frequency between 3 and 30 megahertz (MHz). It is also known as the decameter band or decameter wave as its wavelengths range from one to ten decameters (ten to one hundred meters).

  9. Quad antenna - Wikipedia

    en.wikipedia.org/wiki/Quad_antenna

    A quad antenna is a type of directional wire radio antenna used on the HF and VHF bands. A quad is a Yagi–Uda antenna ("Yagi") made from loop elements instead of dipoles: It consists of a driven element and one or more parasitic elements ; however in a quad, each of the loop elements may be square, round, or some other shape.
