The OE-415A(V)1/SRC antenna group is a twin whip antenna system which provides broadband coverage in the 4-12 MHz frequency range for shipboard transmitting and receiving systems. The antenna system consists of two 35 foot spun aluminum antennas, an impedance matching network and an interconnecting wire-rope feed assembly.

​

The system is intended for use on either the CG or DDG class naval vessels:

​

• CG class vessel - the impedance matching network is CU-2151C/SRC and antenna is an AS-3772B/U

• DDG class vessel - the matching network is CU-2415A/SRC with antenna AS-3772B/U

 

The antennas used in the system are self supporting tapered aluminum tubes with a fibreglass insulator and mounting base.

​

The impedance matching network contains a variable inductor/capacitor to enable optimal VSWR characteristics over the entire 4-12 MHz band. A VSWR of 3:1 or less on 50 Ohms can be achieved over the entire frequency band.

​

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.
