Seachoice Coax Connectors: Purpose-Built for Marine VHF Systems

When your VHF radio is your lifeline on the water, every connection in the signal chain matters. Seachoice has been engineering marine-grade hardware since 1988, and their line of coax connectors reflects the same philosophy that has made the brand a staple aboard recreational and fishing boats alike: practical design, durable materials, and dependable performance in demanding marine environments.

A Complete System of VHF Antenna Connectors

Seachoice's coax connector lineup covers the essential interface points between your coaxial cable and your VHF antenna. The range includes several purpose-matched components that work together as a complete connector system:

• PL-259 VHF Male Connector (19821) — The foundational coax plug compatible with RG58U and 8X cable types. Accepts both the UG-175 and UG-176 reducer adapters, making it adaptable to multiple cable gauges.
• VHF Connector with Adapter Kit (19811) — A convenient combo pairing the PL-259 plug with the UG-175 adapter, pre-matched for RG58U cable installations.
• UG-175 Adapter for RG58U Cable (19831) — The correct reducer when transitioning from PL-259 to the smaller-diameter RG58U coax used on most recreational boats.
• UG-176 Adapter for RG59U Cable (19841) — The companion adapter designed specifically for RG59U cable, fitting the same PL-259 plug body.
• PL-258 Double Female Connector (19851) — A barrel-style coupler that joins two PL-259 cable plugs end-to-end, useful for extending antenna runs or connecting cable assemblies.

All of these connectors are constructed from chrome-plated brass, a material choice that delivers meaningful corrosion resistance in the saltwater and high-humidity conditions common to marine use. The polished chrome finish also provides improved resistance to wear over bare brass alternatives.

ProConnect Compatibility and Cable Extensions

Seachoice's coax connector family is designed to work within their broader antenna accessory ecosystem. Their coaxial cable extensions — available in white and black, in 5-foot, 10-foot, and 20-foot lengths — are fitted with ProConnect FME connectors, a factory-installed system that eliminates the need for large cable penetrations and connector crimping during installation. This makes antenna cable runs cleaner and easier to route through tight spaces in a boat's hull or cabin structure.

Why Choose Seachoice for Marine Coax Connectors?

Seachoice is a brand that is, in their own words, "run for and by boaters," and that focus shows in how their connector lineup is spec'd. Rather than offering generic consumer-grade RF hardware, their VHF fittings are matched to the specific cable types and antenna systems common in recreational marine electronics. The chrome-plated brass construction, the modular adapter system, and the no-hassle warranty policy all add up to a straightforward, reliable choice for anyone wiring or re-wiring a VHF antenna installation. Whether you’re replacing a corroded connector after a season offshore or building a clean new cable run on a fresh installation, Seachoice's coax connectors provide the right fitting for the job.
