RAMI254-EXT
Ground Based Communications
The RAMI254-EXT 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 both VHF and UHF operation modes. It can be deployed atop its 27 foot mast (RAMI5008-FG) or utilized on the ground standing on its tripod base (RAMI5709). 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.
