Glomex 6M - 20' RB-8X Coax f/Glomeasy VHF Antennas - White

The Glomex 6M – 20' RB-8X Coax for Glomeasy VHF Antennas is the replacement coaxial cable that serious boaters and commercial operators depend on to maintain reliable VHF radio performance at sea. Whether you're running coastal routes, offshore fishing, or managing a fleet, this marine-grade coax cable ensures your VHF antenna system delivers clear, uninterrupted communication in all conditions. Built by Glomex, a trusted name in marine antenna systems for decades, this cable is engineered specifically for the Glomeasy VHF antenna platform.

The RB-8X coaxial construction minimizes signal loss over its 20-foot length, critical for maintaining transmit and receive clarity across the VHF marine band (156–162 MHz). The cable's robust shielding protects against electromagnetic interference from engine noise, radar systems, and other onboard electronics—a common problem on vessels with heavy electrical loads. The low-loss design preserves signal strength from the radio to the antenna, ensuring your distress calls, position reports, and routine communications arrive crystal clear. At just 0.95 lbs, it's lightweight enough for easy handling and installation, yet constructed with marine-grade materials that resist salt spray, UV exposure, and the constant flexing that deck-side cables endure.

If your Glomeasy VHF antenna system shows weakened signal strength, intermittent reception, or physical cable damage, replacing the coax with this genuine Glomex replacement will restore full performance. Installation is straightforward—disconnect the old cable from both the radio and antenna connector, route the new 20-foot run to your preferred antenna height, and secure connections finger-tight plus a quarter-turn. This cable is compatible with all Glomeasy VHF antenna models and standard marine radio installations using FME connectors, making it an essential spare for any serious boater who relies on dependable communications.
