The model 21CFJM is a three-function antenna that provides simultaneous operation at UHF, S-band and C-band frequencies. This antenna produces high efficiency, omni-directional, radiation pattern coverage over each of the three frequency bands. It consists of two thin shells that install conformally on a cylindrical shape of approximately 6" in diameter and 12" long. The antenna includes an integral high temperature radome, antenna feed networks and three separate coaxial connectors to provide inter-frequency isolation. This antenna is designed for operation in a high dynamic, military airborne environment. Weight: 1.5 lbs.
