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

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.
The KVLY-TV mast is the tallest structure in the United States, at 2,063 ft (629 m) tall Galesville, Wisconsin WKBT-DT tower. This is a list of the tallest structures in the US that are at least 350 meters, ordered by height.
The diamond-shaped tower was patented by Nicholas Gerten and Ralph Jenner for Blaw-Knox July 29, 1930. [5] and was one of the first mast radiators.[1] [6] Previous antennas for medium and longwave broadcasting usually consisted of wires strung between masts, but in the Blaw-Knox antenna, as in modern AM broadcasting mast radiators, the metal mast structure functioned as the antenna.
