SHIPBOARD CA-3123 AS-2810/SRC BROADBAND VERTICAL DIPOLE ANTENNA Model CA-3123 is a broadband, base-mounted dipole antenna which provides vertically polarized, omnidirectional coverage over the 225 - 400 MHz frequency band for power levels to 100 watts. It is a rugged, lightweight unit sealed within an epoxy fiberglass radome, suitable for prolonged use in a marine shipboard environment. The zenith pattern of the antenna is a figure-eight with maximum signal intensity along the horizon. An electrical isolating section is incorporated into the feed system to provide a balanced feed to the radiating elements and to assure large decoupling from the feed line. The RF input connector is a Type N receptacle in the base. The input VSWR is less than 2.5:1, on 50 ohms, over the entire operating band. CA-3123 has been fully qualified to meet MIL-S-901C for Grade A Shock; MIL-STD-167, Type 1 Vibration; and all Service Conditions of MIL-E-16400F for Class 2 equipments.
