Vest Mounted Antenna System (VMAS) – BNC Tactical Radio Antenna
The Vest Mounted Antenna System (VMAS) BNC is a U.S.-made, body-worn antenna engineered for VHF/UHF handheld radios operating across 30–512 MHz. Optimized for intra-squad communications, the VMAS routes from the handheld radio over the shoulder and into the communicator’s back webbing, keeping vision clear and movement unrestricted.
Durability and Compliance
Protected with an abrasion-resistant sleeve, the VMAS is built to withstand the toughest conditions. It is manufactured with UL and CSA flame-resistant materials (VW-1 rated) and is Berry Amendment compliant, ensuring it meets strict operational standards.

Tactical Advantages
The VMAS BNC offers significant benefits over traditional long whip antennas, including:
-
Improved concealment – body-worn placement reduces signature.
-
Unobstructed movement – no antenna whip in front of the operator.
-
Enhanced performance – optimized for range and reliability across VHF/UHF bands.
-
Standardized BNC interface – quick, secure bayonet-style connection for military and commercial radios.
Adapter Compatibility
No adapter is required for radios with a BNC connector. For maximum versatility, DISCO32 offers a 50% discount on select adapters when purchased with the VMAS:
-
Black BNC → SMA-F: for Baofeng and similar handheld radios.
-
Black BNC → SMA-M: for Yaesu and similar radios.
-
Black BNC → TNC: adapts QD/BNC antennas to TNC military radios.
Backed by a 1-year manufacturer’s warranty, the VMAS BNC provides operators with a reliable, field-proven antenna solution for a wide array of operational scenarios.
FAQs
What radios are compatible with the VMAS BNC?
Any handheld radio with a BNC connector, or with SMA/TNC adapters for Baofeng, Yaesu, and military radios.
Why use a vest-mounted antenna?
Vest mounting keeps the antenna out of the operator’s line of sight, improves concealment, and prevents snag hazards compared to traditional whip antennas.
What frequency coverage does the VMAS BNC provide?
Broadband 30–512 MHz coverage across VHF and UHF tactical bands.
Is the VMAS BNC compliant with U.S. mil
