Seachoice Coax Cable & Extensions

Seachoice Marine Coaxial Cables for VHF Communication

When reliable communication at sea depends on quality connections between your VHF radio and antenna, Seachoice delivers purpose-built marine coaxial cables and extensions designed to withstand the harsh conditions of saltwater environments. As a trusted name in marine electronics accessories, Seachoice has engineered their coax cable and extensions specifically for boaters who need dependable signal transmission in challenging marine applications.

Marine-Grade Cable Construction

Seachoice coaxial cables utilize marine-grade L-195 cable type, which provides superior durability compared to standard automotive or consumer-grade coaxial cables. This construction ensures consistent performance when exposed to moisture, salt spray, and the constant vibration encountered in marine environments. The RG58U white coaxial cable with PL259 fittings on both ends represents their traditional antenna extension solution, available in multiple lengths to accommodate various installation requirements from compact center consoles to larger cruising vessels.

ProConnect FME Technology

One of Seachoice's key innovations in marine coaxial connectivity is their ProConnect system. ProConnect features factory-installed FME connectors with PL-259 adapters and eliminates large holes and crimping of connectors. This design simplifies installation considerably, allowing boaters to complete antenna installations without specialized crimping tools or creating oversized holes in their cabin structures. The factory-installed connectors ensure consistent quality and eliminate the most common source of signal loss in marine VHF systems—poorly crimped field-installed connectors.

Versatile Length Options and Connector Configurations

Seachoice offers their coaxial extensions in practical length options ranging from 5 feet to 20 feet, with both white and black cable colors to match various boat aesthetics and installation preferences. Whether you're replacing a damaged cable run, upgrading to a new antenna location, or extending an existing installation, these pre-terminated cables provide plug-and-play convenience. The 50-ohm impedance rating ensures proper impedance matching with marine VHF equipment, maintaining signal integrity across the entire frequency range used by marine communications.

Complete Connectivity Solutions

Beyond basic extension cables, Seachoice provides a comprehensive range of VHF antenna connectors and adapters that complement their cable offerings. Their line includes PL-259 connectors, UG-175 and UG-176 adapters for different cable sizes, and PL-258 double female connectors for joining cable sections. This complete ecosystem of marine coaxial components ensures that whether you're performing routine maintenance, upgrading electronics, or custom-configuring your communication system, you'll find compatible Seachoice solutions that work together seamlessly for reliable marine VHF performance.
