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

Cellular lattice tower A cell tower in Peristeri, Greece. A cell site, cell phone tower, cell base tower, or cellular base station is a cellular-enabled mobile device site where antennas and electronic communications equipment are placed (typically on a radio mast, tower, or other raised structure) to create a cell, or adjacent cells, in a cellular network.
At the time they were built, they were the tallest towers used for military purposes in the Western hemisphere. [1] The two masts are also the tallest towers used for long wave transmissions in the Western hemisphere. Since the collapse of Warsaw Radio Mast, they may be the world's tallest structures that are electrically insulated from the ground.
In passive mode, the StingRay operates either as a digital analyzer, which receives and analyzes signals being transmitted by cellular devices and/or wireless carrier cell sites or as a radio jamming device, which transmits signals that block communications between cellular devices and wireless carrier cell sites.
Globecom Tower was a 378.25 m (1,240.98 ft) tall guyed mast for military longwave transmission at Northmountain on Pituffik Space Base on Greenland.Globecom Tower, whose design is similar to that of Forestport Tower, is a guyed lattice steel tower with a triangular cross section (sidelength: 4.75 metres), which is anchored in three levels.
Typical GWEN relay node. The Ground Wave Emergency Network (GWEN) was a US Air Force command and control communications system, deployed briefly between 1992 and 1994, intended for use by the United States government to facilitate military communications before, during and after a nuclear war.
Prior to the creation of the DHFCS, the Royal Air Force (RAF) and Royal Navy (RN) operated their own independent high frequency (HF) communications systems. The RAF's Strike Command Integrated Communications System (STCICS), later known as Terrestrial Air Sea Communications (TASCOMM), operated from six sites within the UK whilst the RN system had twelve sites.
