Detailed Description

The OE-418A(V)1/SRC antenna group is a twin whip antenna system which provides broadband coverage in the 10-30 MHz frequency range for shipboard transmitting and receiving systems. The antenna system consists of two 18 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-2241C/SRC and antenna is an AS-3770B/U

  • DDG class vessel - the matching network is CU-2416A/SRC with antenna AS-3773B/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 10-30 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.
