  2. Shortwave broadband antenna - Wikipedia

    en.wikipedia.org/wiki/Shortwave_broadband_antenna

    An ideal “broadband” shortwave antenna would work continuously across much of, if not all of, the shortwave spectrum with good radiation efficiency and minimal compromise of the radiation pattern. Most practical broadband antennas compromise on one of the above: Either they only work on a few relatively narrow slices of the HF radio ...

  3. T2FD antenna - Wikipedia

    en.wikipedia.org/wiki/T2FD_antenna

    [1] [2] It was a popular antenna design during the middle of the 20th century, but fell out of common use during the latter part of the century with the growing popularity of upper HF and VHF frequencies, which needed dipoles with more feasible lengths – only 16 foot (4.9 m) or smaller, as opposed to 70 foot (21 m) quarter-wave antennas ...

  4. Hexbeam - Wikipedia

    en.wikipedia.org/wiki/Hexbeam

    Hexbeam amateur radio antenna. A hexbeam, or hexagonal-beam, is a type of a directional antenna for shortwave, most often used in amateur radio. The name comes from the hexagonal outer shape of the antenna. It may also sometimes be known as a W-antenna, referring to the shape of the driver. The design looks something like an upturned umbrella.

    The discone is a monopole version of a biconical antenna. The name of the antenna describes its shape: A metal disk above a metal cone. The cone points upwards and is made of solid metal, wire mesh, or a skirt of about a dozen sloping wires that outline a cone.

  6. Shortwave bands - Wikipedia

    en.wikipedia.org/wiki/Shortwave_bands

    Shortwave bands are frequency allocations for use within the shortwave radio spectrum (the upper medium frequency [MF] band and all of the high frequency [HF] band). Radio waves in these frequency ranges can be used for very long distance (transcontinental) communication because they can reflect off layers of charged particles in the ionosphere and return to Earth beyond the horizon, a ...

  7. Radio masts and towers - Wikipedia

    en.wikipedia.org/wiki/Radio_masts_and_towers

    For transmissions in the shortwave range, there is little to be gained by raising the antenna more than a half to three quarters of a wavelength above ground level, and at lower frequencies and longer wavelengths, the height becomes infeasibly great (greater than 85 metres (279 ft)). Shortwave transmitters rarely use masts taller than about 100 ...
