Vest Mounted Antenna System TNC 90°
The Vest Mounted Antenna System (VMAS) was designed to be used by U.S. military communicators. This model features a threaded connector for military handheld radio systems (i.e., PRC-163, PRC-152, PRC-148).
The VMAS is a body-worn antenna optimized with handheld radios for intra-squad communications (30-512 MHz). 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 90° 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)
