SO239 to NMO Antenna Mount Adapter – Ring and Pin Set (No Mount Bolt)

The SO239 to NMO Antenna Mount Adapter Ring and Pin Set lets you convert an existing SO239-style antenna mount to NMO-style hardware quickly and securely. This is the ring and pin set only — mount bolt is not included.

Why Convert to NMO?

NMO mounts offer a low-profile, secure engagement and broader compatibility with today's antenna lineup. This set bridges the gap between older SO239-style mounts and newer NMO antenna systems, making it a cost-effective upgrade path.

Ideal For

• Vehicle and mobile antenna upgrades
• Replacing worn SO239 mount hardware
• Standardizing mount types across multiple radio installations
• CB, ham radio, and two-way radio antenna conversions

Package Includes

• 1 × SO239 to NMO Adapter Ring
