This specification covers the design, development,
performance, and test requirements for the Antenna Group, OE-418(V)/SRC,hereinafter referred to as the antenna group. The antenna group is a nominal 5.5-meter (m) (18-foot (ft)) twin-whip configuration with matching network
enclosure. The antenna group can be impedance matched to provide broadband frequency coverage in the 10-megahertz (MHz) to 30-MHz range for high frequency (HF) shipboard transmitting systems.
