The elevation pattern of the antenna is a figure-eight with maximum signal intensity along the horizon and a half-power beam width of 80°. The inherent balanced dipole design and broadband impedance characteristics make the performance of this antenna relatively insensitive to its mounting environment.
The RF input connector is a Type N receptacle recessed in the base. The input VSWR on 50 ohms is less than 3.5:1 over the operating band.
CA-1177 is designed to meet MIL-S-901C for Grade A Shock; MIL-STD-167, Type I Vibration; and all Service Conditions of MIL-E-16400F for Class 2 equipment.
