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 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.
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.

A tower array is an arrangement of multiple radio towers which are mast radiators in a phased array. [1] They were originally developed as ground-based tracking radars. [2] Tower arrays can consist of free-standing or guyed towers or a mix of them. Tower arrays are used to constitute a directional antenna of a mediumwave or longwave radio station.

Modern folded unipole antenna with six skirt wires surrounding a round solid metal mast. The skirt wires are held away from the mast by stand-off posts with insulated ends. The folded unipole antenna is a type of monopole mast radiator antenna used as a transmitting antenna mainly in the medium wave band for AM radio broadcasting stations.
Masts of RKS Liblice 2 as viewed from a distance. Close-up view of the masts of the towers. The RKS Liblice 2 are two 355 m (1,165 ft) tall guyed masts located east of Prague near Liblice, in close proximity of the RKS Liblice 1. These lattice steel towers are built 120 m (390 ft) apart from each other, what formed a slightly directional ...
