The assembly is comprised of two independent broadband elements that are housed within an epoxy fiberglass radome with an aluminum base and top flange. A feedthrough cable runs from the base to the top of the antenna so that an AS-390 or other antenna type can be mounted on the upper flange. An adapter kit is provided to facilitate the top mounting provision. Type N female connectors are provided for each end of the feedthrough RF cable and at the antenna base for the two UHF input connectors.
The CA-1181 antenna is designed to meet the Shock Requirements of MIL-S-9010, the Vibration Requirements of MIL-STD-167-1, Type I and II, and the Environmental Requirements of MIL-E-16400H.
