Laird Technologies 3/4" Brass Mount

The Laird Technologies 3/4" permanent hole brass mount provides a fixed NMO base for vehicle roof installations. It accepts Motorola-style mobile antennas operating from 0 to 1000 MHz. The all-brass construction ensures durability and reliable electrical contact. A 1 1/8 inch - 18 thread size secures the antenna element to the base.

Installers needing a permanent roof mount

This mount suits installers fitting a single Motorola-style antenna to a metal roof panel with a 3/4 inch hole. It is not for magnetic or temporary mounting applications. Buyers who need a no-drill solution should look at alternative mounting styles. The kit requires separate cable and connector purchase to complete the installation.

Frequency headroom up to 1000 MHz

The mount comfortably handles VHF and UHF mobile bands within the 0 to 1000 MHz range. It runs out of specified headroom above 1000 MHz, so it is not suited for higher microwave frequencies. The brass body provides a solid ground plane for the connected antenna. Cable loss and connector choice will determine final system performance.
