RAMI254EXT-LB
Ground Based Communications
The RAMI254EXT-LB is a 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 VHF, UHF, and L-Band operation modes. It can be deployed atop its 27 foot mast (RAMI5008-FG) or utilized on the ground standing on its tripod base (RAMI2210). 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 two 40 foot LMR-400 transmission lines with an in line adapter (antenna to diplexer) and two 5 foot RG-223 transmission lines (diplexer to radio set). Additional components for full assembly and erection (mast or ground deployment) are included in the transit bag.
