Structurally, the only difference is that some mast radiators require the mast base to be insulated from the ground.
An antenna farm, satellite dish farm or dish farm is an area dedicated to television or radio telecommunications transmitting or receiving antenna equipment, such as C, K u or K a band satellite dish antennas, UHF/VHF/AM/FM transmitter towers or mobile cell towers.
The first tower he built was for airport use. [1] ROHN first began producing antenna towers for home television reception, and subsequently expanded its product line to include the manufacturing of telecommunication towers and other communication products, including broadcast towers of up to 2,000 feet high.

The radio frequency current from the transmitter is supplied to the antenna through a cable called the feedline.The antenna tuning hut contains a matching network made of high wattage capacitors and inductors (coils) that in combination match the antenna's impedance to the feedline, to efficiently transfer power into the antenna.
A second, smaller, 30 m (98 ft) tall tower was installed by the US Coast Guard in the autumn of 1961 as part of a LORAN-A network paired with Greenland. The LORAN-C scheme closed in 1994. In 1991, the original RÚV 1930 longwave transmitter tower at Vatnsendi (near Reykjavík) collapsed.

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.
