Abstract : An array system is described which covers an 8:1 frequency range in two subbands at VHF. Four beams are formed at right angles in each subband, which are selected by switching, and are independently selectable in each subband. The low-frequency subband uses wire-outline endfire complementary pairs and the high-frequency band uses endfire monopole pairs around a common central reflector. The system will fit on small vehicles, such as troop carriers, tanks, and helicopters. Patterns, input impedances and band-to-band isolation are presented for a full-scale mock-up.
