Use this 32' cable to connect your antenna to your compatible Garmin chartplotter.Chartplotters are excellent tools that let you navigate everything from your favorite fishing spots to adventures in unknown waters — but they revert to paper charts with zoom functionality when they aren't connected to an antenna! Since that completely defeats the purpose of all the modern chartplotting technology, we offer this solution: put your antenna somewhere it gets signal and connect your device using this antenna cable. Problem: solved. Happy boating!SpecificationsCompatibility: AIS 600 (sold separately); GA 30 GPS Antenna (sold separately)Length: 30'Color: White with silver metal connectors
