Overview
The Vest Mounted Antenna System (VMAS) BNC 90° is an American-made, body-worn antenna engineered for VHF/UHF handheld radios (30–512 MHz). Designed for intra-squad communications, the VMAS routes from a handheld radio, over the shoulder, and into the operator’s back webbing—improving mobility, visibility, and tactical concealment.
Durability and Safety Standards
Protected by an abrasion-resistant sleeve, the VMAS BNC 90° is built to withstand cuts and wear in harsh environments. It is UL/CSA flame resistant (VW-1) and Berry Amendment compliant, meeting stringent U.S. military and safety requirements.
Operational Advantages
-
Unobstructed movement – routes antenna behind the operator without blocking vision.
-
Low signature – improved concealment versus traditional long whip antennas.
-
Reliable performance – optimized for tactical comms across 30–512 MHz.
-
Durable build – abrasion-resistant, flame-rated, and field-proven.
