Cage aerial

From Wikipedia, the free encyclopedia

A Cage aerial is a radio antenna, which consists of several parallel running wires, which are radialsymmetrically arranged around a tower or a mast. An advantage of the cage aerials is the fact that the carrying tower or carrying mast can be grounded, which facilitates its use for other radio services, for example as carrier mast for the UHF/VHF range, which comes statics because of the absence of the basement isolation to property and also facilitates the supply of the flight safety beaconing. Cage aerials were established in the last decades in different variants for broadcasting stations in the longwave- and mediumwave band.
