Multi-Band VHF/UHF Communications Antenna

The 21-50-62-1 is a rugged multifunction VHF/UHF communications antenna designed for airborne applications. A high strength vertical shell houses 30 - 88 and 225 - 400 MHz co-located linear elements with a single coaxial connector to suit a combined VHF & UHF line of sight “LOS” communications radio. Footprint is compatible with Collins 437S1H and Chelton 12-437 series antennas. The use of top loading disc optimises the efficiency in the VHF and the antenna provides omnidirectional radiation throughout the operating frequency range.
