SHIPBOARD CA-3124, AS-2809/SRC BROADBAND VERTICAL DIPOLE ANTENNA Model CA-3124 is a broadband, base-mounted dipole antenna which provides vertically polarized, omnidirectional coverage over the 115-162 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 figureeight 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. A dc static drain path is provided across the feedpoint. CA-3124 has been fully qualified to meet MIL-S901C for Grade A Shock; MIL-STD-167, Type I Vibration; and all Service Conditions of MIL-E16400F for class 2 equipments.
