The RAMI254 is a direct replacement for the OE-254/GRC Antenna Group. It is comprised of fewer piece parts,
allowing for quicker assembly and erection, along with being capable of both VHF (30-88 MHz) and UHF (225-
450 MHz) operation modes. It can be deployed atop its 27 ft. mast or utilized on the ground standing on its tripod
base. It is manufactured to meet the mechanical and environmental specifications as called out in MIL-PRF-49204
(OE-254/GRC specification). The antenna comes complete with 70 ft. RG-213 transmission line (antenna to
diplexer) and two 5 ft. RG-213 transmission lines (diplexer to radio set). Additional components for full assembly
and erection (mast or ground deployed) are included in the transit bag.

The AS-3900A/VRC Antenna is the newest U.S. Army Vehicular Antenna System designed to perform with the SINCGARS Radio System. The antenna is a center-fed antenna which can withstand the application of 20,000 VRMS to its upper section and 10,000 VRMS to its center section without adverse effect to the antenna or the radio. The antenna is produced to U.S. Army CECOM Specification A3148018 and has successfully shown Nuclear Survivability. The antenna has also been used for back-up communications systems for ground-based installations which are also mobile such as SAM batteries like the Patriot.
