2. Radio masts and towers - Wikipedia

   en.wikipedia.org/wiki/Radio_masts_and_towers

   The antenna used for broadcasting through the 1920s was the T-antenna, which consisted of two masts with loading wires on top, strung between them, requiring twice the construction costs and land area of a single mast. [2] (pp 77–78) In 1924 Stuart Ballantine published two historic papers which led to the development of the single mast antenna.

3. Guyed mast - Wikipedia

   en.wikipedia.org/wiki/Guyed_mast

   Guyed masts are frequently used for radio masts and towers. The mast can either support radio antennas (for VHF, UHF and other microwave bands) mounted at its top, or the entire structure itself can function as a mast radiator antenna (for VLF, LF, MF). In the latter case, the mast needs to be insulated from the ground. Guyed radio masts are ...

4. Guy-wire - Wikipedia

   en.wikipedia.org/wiki/Guy-wire

   A sailboat's mast is supported by shrouds (side-to-side) and stays (fore-and-aft) – nautical equivalents of guy wires.. A guy-wire, guy-line, guy-rope, down guy, or stay, also called simply a guy, is a tensioned cable designed to add stability to a freestanding structure.

5. 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]

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. 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 ...

   Still, Trump's nomination of Scott Bessent to the top Treasury post raised hopes that tariffs will be more measured. And with only 21 trading days left in the year, analysts, investors, and market ...

9. Mast radiator - Wikipedia

   en.wikipedia.org/wiki/Mast_radiator

   An ideal monopole antenna radiates maximum power in horizontal directions at a height of 225 electrical degrees, about ⁠ 5 / 8 ⁠ or 0.625 of a wavelength (this is an approximation valid for a typical finite thickness mast; for an infinitely thin mast the maximum occurs at / = 0.637 [6]) As shown in the diagram, at heights below a half ...
