Motorola RRDN5461A 3/4" Brass Roof Mount with 17ft RG58 Cable

Description

3/4-Inch Brass Vehicle Roof Antenna Mount

Commercial-grade 3/4-inch brass NMO roof mount with integrated 17-foot RG58A/U coaxial cable for mobile radio transceivers.

The Motorola RRDN5461A is a heavy-duty 3/4-inch brass vehicle roof antenna mount engineered for professional mobile radio installations. Designed to attach mobile antennas securely through a standard 3/4-inch hole in a vehicle's metal roof or trunk lid, this permanent mount establishes a solid mechanical hold and low-resistance ground plane connection essential for optimal RF signal performance.

Equipped with a solid brass mounting stud and a factory-attached 17-foot (204-inch) RG58A/U flexible coaxial cable, the Motorola RRDN5461A provides generous cable length to route wiring cleanly beneath vehicle headliners and trim panels to under-dash or trunk-mounted transceivers. Built to withstand extreme road vibration and weather exposure, this genuine OEM antenna mount serves as our primary factory-grade replacement for legacy third-party 3/4" NMO mounts including the TE Connectivity MB8, E/M Wave EM-M11001-058, PCTEL NMO58U-NC, and PCTEL MAXRAD BMA-NC.

The Motorola RRDN5461A is the updated version of the Motorola RRDN5461.
