The Vest Mounted Antenna System (VMAS) BNC is a US-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.

Tech Note: Not meant for use with for Motorola APX Radios

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/commercial 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.

Compatibility note: Designed for APX-series deployments using BNC terminations. Verify your radio/antenna interface before ordering. Quick-disconnect hardware style may vary by production batch; function and fit remain equivalent.

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.
