Description

3/4-Inch NMO Mounting Bracket for Non-Destructive Vehicle Installations

Secure your mobile radio antenna inside trunk seams and fender grooves without drilling holes in exterior body panels.

The Atlantic Radio TMB34B-AR Trunk Mount L-Bracket is a commercial-grade, heavy-duty mounting solution engineered for standard mobile communication setups. Featuring a precision-cut 3/4-inch center hole, this bracket is specifically optimized to host industry-standard NMO style cable mounts and mobile antennas. Its clean right-angle geometry allows field technicians to establish a high-stability antenna base along trunk edges, vehicle hoods, or flat vertical surfaces.

This right-angle mounting bracket is ideal for leased corporate fleets, public safety vehicles, and commercial transport trucks where drilling a permanent hole through the roof or trunk exterior is restricted. Fabricated from premium-grade stainless steel and covered in a highly durable black powder coat finish, it withstands severe weather exposure, high highway wind resistance, and automated car wash systems. The bracket attaches directly into hidden body gutters using the included installation screws, preserving the outer vehicle resale value while maintaining a professional, low-profile appearance.
