Garmin GPS Antenna Cable w/BNC Connectors - 10M

The Garmin GPS Antenna Cable with BNC Connectors – 10M is a marine-grade connectivity solution designed for serious anglers and boaters who depend on precise GPS chartplotting for navigation and fish finding. Whether you're running a multi-antenna setup, extending your primary GPS receiver to a distant location on the helm, or replacing a damaged original cable, this 32-foot extension cable bridges the gap between your Garmin chartplotter and antenna with reliable signal integrity. Built to withstand the harsh salt spray, UV exposure, and constant vibration of offshore and freshwater environments, this cable is essential for maintaining chart accuracy and sonar performance when stock antenna placement falls short of your operational needs.

The cable features military-spec BNC connectors that ensure weathertight connections resistant to corrosion and signal loss—critical when you're miles offshore or navigating tight channels where a dropped satellite fix can cost you fish or safety. The 10-meter (32-foot) length provides ample routing flexibility, allowing you to position your antenna away from electronic noise sources, metal structures, or cabin obstructions that degrade GPS acquisition. Shielded construction minimizes electromagnetic interference from radar, VHF radio, and engine ignition systems, preserving the clean signal necessary for consistent position accuracy and waypoint recording. The marine-rated jacket resists UV degradation, ozone, and salt-air contamination better than standard coax, extending service life across multiple seasons of heavy use.

This cable is ideal for retrofit installations on vessels with helm stations far from optimal antenna mounting points, for anglers upgrading to high-performance positioning systems, and for commercial operators requiring redundant or remote antenna arrays. The BNC termination is standard across Garmin's lineup of compatible chartplotters, including legacy and current-generation units, making this a reliable spare or replacement for any Garmin GPS-enabled vessel. Installation is straightforward—simply disconnect the old cable at the antenna connector and chartplotter input, route the new cable through your chosen path, and reconnect to the same BNC ports. Always verify your chartplotter model's antenna port specification before ordering to confirm compatibility.
