The vest mounted antenna system (VMAS) is a body-worn antenna optimized to work with handheld radios in the intra-squad communications role. The VMAS runs from a handheld radio over the shoulder and threads into the webbing on the back of the communicator.
The VMAS is covered with an abraded sleeve to resist cuts and abrasions. The material has a UL and CSA flame resistant rating of VW-1 and is Berry Amendment compliant.
The VMAS provides the radio operator several tactical advantages compared to long whip antennas. Communications link performance is maintained without hindering the users vision or movement, while the lack of signature helps provide better tactical concealment. Unsurpassed range, performance, and construction make the VMAS the antenna of choice for VHF/UHF tactical radio operators.
The TNC VMAS easily connects to military and commercial handheld radios via the threaded TNC connector. Black low loss RF hardware is standard. Backed by a 1-year manufacturer's warranty (outlined in terms of service).
No adapters needed when used with PRC-163, PRC-148, PRC-152 or similar radio.
