A mast radiator or mast antenna is a radio tower or mast in which the whole structure is an antenna. Mast antennas are the transmitting antennas typical for long or medium wave broadcasting. Structurally, the only difference is that some mast radiators require the mast base to be insulated from the ground.
Guyed radio masts are typically tall enough that they require several sets of guy lines, 2 to 4, attached at different heights on the mast, to prevent them from buckling. An exception to multiple guys was the Blaw-Knox tower , widely used during the 1930s, whose distinctive wide diamond ( rhomboidal ) shape gave it the shear strength that it ...

A typical mast radiator and antenna tuning hut of an AM radio station in Chapel Hill, North Carolina, U.S.. 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.
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.
An amateur radio cage 'T'-antenna 18-metre-high (60 ft) by 27-metre-long (90 ft) built in 1922, owned by the Historic Radio Engineers Club, Riverhead, New York. The conductor is made of a 'cage' of 6 wires held apart by wooden spreaders. This antenna achieved transatlantic contacts on 1.5 MHz, at a power of 440 W.
A typical mast radiator monopole antenna of an AM radio station in Chapel Hill, North Carolina. The mast itself is connected to the transmitter and radiates the radio waves. It is mounted on a ceramic insulator to isolate it from the ground. The other terminal of the transmitter is connected to a ground system consisting of cables buried under ...
