Laird Technologies Antenna Mount 17 ft 240-Series FME-Female 3/4 Hole NMO

Antenna mount with 17 ft cable

This brass NMO mount fits a 3/4-inch hole and terminates in an FME-Female connector. The 17 ft LMR-240 cable is supplied loose for custom routing during vehicle installation. It is suited for mobile radio setups that require a permanent through-roof or bracket fixture. Installers who need a different connector type or a shorter run will need a different assembly.

Sustained signal integrity

The LMR-240 cable construction maintains consistent impedance over the full 17 ft length during extended transmit cycles. Its low-loss dielectric reduces attenuation compared with thinner coaxial types when the radio keys for long periods. The crimp-style FME termination preserves contact reliability under vibration without requiring field soldering. Users needing lower loss for very long runs should evaluate alternative cable grades.

Thermal and power profile

The passive mount and coaxial cable generate no heat and draw no electrical power during operation. Brass hardware resists corrosion from road salt and weather exposure without active cooling. The assembly adds no audible noise to the vehicle cabin. Installers should ensure the mounting surface is grounded to the vehicle chassis for optimal RF performance.
