A mast radiator (or 'radiating tower') is a radio mast or tower in which the whole structure itself functions as an antenna. This design is commonly used for transmitting antennas operating at low frequencies, in the VLF, LF and MF ranges, in particular those used for AM broadcasting. The metal mast is electrically connected to the transmitter. Its base is usually mounted on a nonconductive support to insulate it from the ground. A mast radiator is a form of monopole antenna.
Famous quotes containing the word mast:
“Alas for America as I must so often say, the ungirt, the diffuse, the profuse, procumbent, one wide ground juniper, out of which no cedar, no oak will rear up a mast to the clouds! It all runs to leaves, to suckers, to tendrils, to miscellany. The air is loaded with poppy, with imbecility, with dispersion, & sloth.”
—Ralph Waldo Emerson (1803–1882)
