TH340 (2M) Simultaneous 2-Channel Communications
The AN/PRC-148F IMBITR is a small, lightweight, rugged 2-channel radio that equips Warfighters with simultaneous narrowband and wideband secure Type-1 communications, enabling tactical command and control communications in a variety of challenging environments. The narrowband channel operates all legacy tactical waveforms including: VHF/UHF LOS, SINCGARS, HAVEQUICK, as well as commercial SATCOM. The Wideband channel operates the WREN-TSM™ and WREN-NB waveforms from TrellisWare® Technologies, Inc. TSM delivers superior voice and data communications across harsh multi-path and unpredictable dynamic areas, such as caves, on board ships, and urban operational settings. WREN-NB is a resilient waveform designed to operate in near-peer threat environments which combines resilient narrowband fast frequency
hopping waveform with tactical MANET.
