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
Partially guyed towers in which at least one basement of the guy anchors is on the ground are more rare. The placement of guy basements across a broader geometric base allows for a mast much taller than the free-standing basement tower, and the integration of tower and mast should be considered in all facets of construction and maintenance.
These towers can have a triangular or a square cross section, with each leg supported on an insulator. A disadvantage is the wide base of the tower distorts the vertical current pattern on the tower, reducing the radiation resistance and therefore the radiated power, so guyed masts are preferred.

Three electronic equipment shelters; two located near the perimeter of the site, and one at the base of the tower containing an antenna-tuning unit (ATU) UHF and LF receive antennas mounted on either a 10 ft. mast, 30 ft. light pole, or 60–150 ft. tower.
Transmission tower in Toronto, ON Single-circuit three-phase transmission line Transmission towers on a hill field. Three-phase electric power systems are used for high voltage (66- or 69-kV and above) and extra-high voltage (110- or 115-kV and above; most often 138- or 230-kV and above in contemporary systems) AC transmission lines.
