Seachoice 19771 RG-58U Coaxial Antenna Cable Assembly — 20 ft
The Seachoice 19771 is a ready-to-install 20 ft RG-58U coaxial antenna cable assembly, pre-terminated with PL-259 connectors on both ends. Connect it directly between your VHF radio and antenna without any cutting, soldering, or connector assembly. The white jacket blends cleanly with white fiberglass hulls and interior cable runs, and the 20 ft length suits larger vessels, longer helm-to-antenna runs, or installations where the radio and antenna are separated by a significant distance. A practical, no-fuss solution for new installs or replacing an existing cable run.

Parts Desk Insights
The 19771 is the right pick when a customer has a larger vessel or a helm-to-antenna run that the 10 ft cable won’t reach. It’s also the length we recommend when the customer isn’t sure of the exact run distance — a little extra cable is easier to manage than coming up short. If 20 ft is more than needed, the Seachoice 19761 (10 ft) and Seachoice 19781 (5 ft) are the shorter options. For runs beyond 20 ft or where lower signal loss is a priority, the Shakespeare 35 ft Marine Antenna Cable Kit and Shakespeare 50 ft Marine Antenna Cable Kit offer pre-terminated low-loss cable in longer lengths.
