GROUND/MOBILE CA-1079 SERIES LOW POWER VHF/UHF MULTICHANNEL ANTENNAS Model CA-1079 is a low-power, general purpose communications antenna for use when VHF (115 - 162 MHz) and UHF (225 - 400 MHz) channels are to be used simultaneously. Various combinations of VHF and UHF radiators, enclosed in a single housing, provide independent, broadband, vertically polarized coverage. Use of this antenna in multichannel communications systems can substantially reduce the total space requirements and significantly improve the overall system performance. The antenna radome has an integral base mounting flange with coaxial Type N input connectors on the underside for each channel. An optional base adaptor is available which elevates the base above the mounting surface sufficiently to permit cable connections to be made from the side. The antenna can also be supplied without a base plate for side mounting to a vertical pipe. CA-1079 is intended to provide interference-free ground-to-air and ground-to-ground communications. Because of its inherent broadband characteristics, the unit is relatively insensitive to its mounting location and the surrounding environment. It has been designed to meet MIL-STD-167, Type I Vibration; and the Service Conditions of MIL-STD-810B (operating temperature -40 to +55C).
