2. Guy-wire - Wikipedia

   en.wikipedia.org/wiki/Guy-wire

   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. They are used commonly for ship masts, radio masts, wind turbines, utility poles, and tents. A thin vertical mast supported by guy wires is called a guyed mast.

3. Guyed mast - Wikipedia

   en.wikipedia.org/wiki/Guyed_mast

   Partially guyed towers are typically used when a very high tower for FM and TV transmission is required, while also carrying antennas for directional radio services at a much lower height. In such cases the antennas for directional radio services are mounted on the top of the free-standing part of the tower, while the guyed mast on its top ...

4. Radio masts and towers - Wikipedia

   en.wikipedia.org/wiki/Radio_masts_and_towers

   A radio mast base showing how virtually all lateral support is provided by the guy-wires. The terms "mast" and "tower" are often used interchangeably. However, in structural engineering terms, a tower is a self-supporting or cantilevered structure, while a mast is held up by stays or guy-wires. [1] A mast

5. Counterpoise (ground system) - Wikipedia

   en.wikipedia.org/wiki/Counterpoise_(ground_system)

   Counterpoises are typically used in antenna systems for radio transmitters where a good earth ground connection cannot be constructed.. Monopole antennas used at low frequencies, below 3 MHz, such as the mast radiator antennas used for AM broadcasting, require the radio transmitter to be electrically connected to the Earth under the antenna; this is called a ground (or earth).

6. Radial (radio) - Wikipedia

   en.wikipedia.org/wiki/Radial_(radio)

   The ends of the wires nearest the antenna base are connected to the antenna system electrical ground, and the far ends are either unconnected, or connected to metal stakes driven into the earth. Top loading radial wires. Symmetrically arranged radial wires may also be attached to the top of an antenna, running horizontally away from its apex ...

7. Antenna types - Wikipedia

   en.wikipedia.org/wiki/Antenna_types

   Consists of a long horizontal wire crossing the gap between two towers, with a vertical wire attached to the center of the horizontal wire, hanging down from its center; the dangling vertical wire is the radiating part of the antenna. The wires outline the shape of the letter 'T', hence the name.

9. Mast radiator - Wikipedia

   en.wikipedia.org/wiki/Mast_radiator

   A mast radiator (or radiating tower) is a radio mast or tower in which the metal structure itself is energized and functions as an antenna. This design, first used widely in the 1930s, is commonly used for transmitting antennas operating at low frequencies , in the LF and MF bands, in particular those used for AM radio broadcasting stations.
