PURPOSE AND STRUCTURE
Antennas have proper bearing structure, consisting of emitting structure, the bearing with power divider and lattice girder, supporting the approach and bolting of out put port of the main feeder cable. Antenna is installed on the top of the bearing, roof of a high building, and at the band of bearing metalware.
