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. This design, first used widely in the 1930s, is commonly used for transmitting antennas operating at low frequencies, in the LF and MF bands, in particular those used for … See more
Most mast radiators are built as guyed masts. Steel lattice masts of triangular cross-section are the most common type. Square lattice masts and tubular masts are also sometimes used. To ensure that the tower is a … See more
The vertical or monopole antenna was invented and patented by radio entrepreneur Guglielmo Marconi in 1896 during his development of the first practical radio See more
A single mast radiator is an omnidirectional antenna which radiates equal radio wave power in all horizontal directions. Mast radiators radiate vertically polarized radio waves, with most of the power emitted at low elevation angles. In the See more
