ABSTRACT:
An omindirectional antenna includes one or more dipole radiators. Each dipole radiator comprises a first and second cylindrical radiating element. Each radiating element includes an end plate for mounting the radiating element coaxially on a tubular mast. The cylindrical radiating elements, end plates and tubular mast are all DC connected. A feed line is provided which may extend through the center of the mast and exit at an opening for connection to a secondary feed line. The secondary feed line is connected to an end of one of the cylindrical radiating elements of each pair of elements for each dipole radiator. The feed line is connected to the end of the cylindrical radiating element opposite the end plate. The configuration of the dipole radiators is such that the radiator functions an an RF choke for the adjacent radiators. An additional single cylindrical element can be provided at the end of a plurality of dipole radiators to provide RF choking for the immediately adjacent dipole radiator. A plurality of main feed lines may be included to extend through the center of the mast with corresponding openings for connection to secondary feed lines.
