NMO to SO239 Adaptor Connect NMO Antenna Mounts to Standard UHF PL259/SO239 Coaxial Systems

Product Overview

The GME AD510 is an NMO to SO239 adaptor that bridges the NMO antenna mounting and connector system with the standard UHF SO239/PL259 coaxial connector family. It allows NMO-mounted antennas to connect to standard UHF coaxial cables and radio equipment, or allows standard PL259 coaxial connections to be used with NMO antenna hardware.

Features & Benefits

  • NMO to SO239 adaptor — bridges the NMO antenna mount/connector system with the standard UHF coaxial SO239/PL259 connector family
  • Extends NMO compatibility — allows NMO antenna hardware to interface with standard UHF CB and radio coaxial cable assemblies
  • Genuine GME accessory — manufacturer-supplied adaptor for use with NMO-mounted GME and compatible antenna systems

Frequently Asked Questions

What is an NMO mount and where is it used?

NMO (New Motorola Mount) is a flush-mount antenna system originally developed by Motorola and widely adopted across commercial two-way radio, emergency services, and professional vehicle radio installations. An NMO mount involves drilling a hole in the vehicle roof or surface and inserting the NMO stud through it, creating a flush weatherproof mount. The NMO connector at the top of the stud accepts a wide range of antenna whips designed for the NMO standard. NMO is common in commercial fleets, taxis, and emergency vehicle radios.

What does this adaptor allow me to do?

The AD510 bridges the NMO connector system with the standard UHF SO239 socket, allowing NMO antenna hardware to work with standard PL259/SO239 UHF radio coaxial connections, or allowing a standard coaxial cable to connect to NMO-based equipment. The exact direction and application should be confirmed with GME for your specific installation.

How does the AD510 differ from the AD5xx FME adaptor series?

The AD5xx series (AD501–AD505) all involve the FME compact connector on one end, bridging to BNC, PL259, TNC, and Mini UHF. The AD510 is a completely separate product bridging NMO (a mount-based connector system) to SO239 (UHF female socket) — no FME connector is involved.

What antenna thread or mount does NMO use?

NMO uses a proprietary locking connector that is independent of the thread-based standards (5/16" TPI, BSW, M6) seen on other antenna bases. It uses a bayonet-style twist-lock mechanism where the antenna whip base locks onto the NMO stud. NMO whips are not interchangeable with 5/16" or BSW thread antenna bases without an adaptor.

Is this sold as a single piece?

One adaptor is included per purchase.
