Cophasal horizontal wideband array antennas for transmitting with asymmetric output
Abstract
Type SGDRA cophasal horizontal wideband antennas for transmitters with asymmetric (single-stage) output are described. An antenna of this kind consists of rigid shunt vibrators and an asymmetric feeder channel. The latter is formed by symmetric overhead feeders, a symmetrizing device being available for operation with a single-stage transmitter. Two typical construction are: one tower section with four tiers of vibrator groups and two tower sections with eight tiers of vibrator groups on each, with an adapter from symmetric to asymmetric feeder channel in each case. Various arrangements for power feed are possible, coaxial cables being most suitable for this purpose. The performance characteristics of these antennas are discussed.
