| Description: | The
OE-416A/SRC antenna group is a twin-whip antenna system which
provides broadband coverage in the 4-30 MHz frequency range for HF
shipboard receiving systems. The antenna system consists of
two 14 foot spun aluminum antenna, a coaxial cable termination box,
and an interconnecting wire-rope mechanism. The system is intended for use on an OA-9242(V)4/SR tilt mechanism. The antennas used in the system are self supporting tapered aluminum tubes with a fibreglass insulator and mounting base. The termination box J-3152B/SRC contains three main components: - a bowl insulator - a coaxial type LC input connector for interconnection to associated receiving equipment. - a fixed static charge resistor EMP protection is also provided. The system has been qualified to MIL-S-901C for shock, MIL-STD-167 for Type 1 vibration, and all the service conditions of MIL-E-16400. |
