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.

A cage antenna (British cage aerial) is a radio antenna where a conventional design has been augmented by replacing a single long conductor with several parallel wires, connected at their ends, and held in position by ring spacers or support struts mounted on a central mast (if any). The "cage" is either mounted around a central mast (either ...
By 1930 the disadvantages of the T antenna led broadcasters to adopt the mast radiator antenna. [9] One of the first types used was the diamond cantilever or Blaw-Knox tower. This had a diamond (rhombohedral) shape which made it rigid, so only one set of guy lines was needed, at its wide waist. The pointed lower end of the antenna ended in a ...
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 ...
With certain versions of the Country Squire, an AM/FM-Cassette stereo with a combined and fully integrated Citizens' Band (CB) two-way radio, and replacement dual-purpose automatic antenna (with only one visible difference; the aerial mast was a larger diameter, and black-band at approximately half-way up).
The shape of the antenna resembles the letter "T", hence the name. The transmitter power is applied, or the receiver is connected, between the bottom of the vertical wire and a ground connection. [1] A closely related antenna is the inverted-L antenna. This is similar to the T-antenna except that the vertical feeder wire, instead of being ...
