High Quality Content by WIKIPEDIA articles! A partially guyed tower is a tower structure which consists of a free-standing basement, in most cases of concrete or of lattice steel with a guyed mast on the top. The anchor basements of the guyed mast can be on the top of the tower or on the ground.Partially guyed towers can be used e.g. when a very high tower for FM and TV transmission is required, which should also carry antennas for directional radio services in a much lower height. In this cases the antennas for directional radio services are mounted on the top of the free-standing part of the tower, while the guyed mast on its top carry the FM and TV antennas. They can be also used in order to upgrade small stable towers (like watertowers) with a long antenna mast for FM and TV broadcasting. However their use is rare, and done only in some European countries.
