Glomex FME Female to SO-239 Adapter f/Glomeasy Antennas

The Glomex FME Female to SO-239 Adapter for Glomeasy Antennas bridges two industry-standard connector types, enabling seamless integration between modern FME-equipped antennas and legacy SO-239 (UHF) radio systems found throughout recreational and commercial vessels. After years running marine electronics across different generations of boats, this adapter solves a common compatibility challenge: upgrading antenna systems without replacing entire radio installations. Whether you're retrofitting a new Glomeasy antenna to an older VHF or DSC radio, or consolidating multiple antenna feeds on a crowded mast, this compact adapter delivers reliable RF connectivity without signal loss.

Built by Glomex Marine Antennas—a trusted name in marine RF solutions—this FME-to-SO-239 adapter uses precision-engineered brass connectors and gold-plated contacts to ensure impedance matching at 50 ohms and minimal return loss during transmission and reception. The female FME end accepts modern antenna connectors, while the SO-239 (male UHF) end screws directly into your existing radio's antenna jack. At just 0.15 lbs and compact in profile, it introduces negligible weight topside and presents zero installation complications; simply screw both ends hand-tight and verify RF continuity. The adapter's robust construction resists corrosion, salt spray, and thermal cycling—essential durability for saltwater and freshwater environments alike.

Boaters upgrading to Glomeasy antenna systems, technicians managing mixed-generation marine radio fleets, and anglers adding secondary VHF or SSB antennas to existing mast systems benefit most from this adapter. It pairs seamlessly with any Glomeasy antenna model and works with all SO-239-equipped marine radios—VHF, AM/FM, SSB, or multi-band systems. Installation is straightforward: remove the existing antenna connector and thread the adapter's SO-239 end into the radio jack, then attach your FME-terminated antenna cable or antenna directly to the female FME port. For maximum signal integrity on long cable runs, keep coaxial connectors tight and store the adapter in a dry locker when not in use.
