Furuno 7-Pin NMEA Antenna Cable — 25 Metres
This 25-metre Furuno antenna cable extends the connection between a compatible Furuno GPS or navigation antenna and the chartplotter or navigator at the helm. It uses Furuno’s 7-pin NMEA connector and is the correct solution when the standard antenna cable length doesn’t reach your helm installation — common on larger vessels where the antenna is mounted high on a mast or radar arch well away from the electronics.
At 25 metres, it covers the full cable run on most mid-size to larger vessels without requiring multiple extensions or signal degradation from excessive cable length.

Parts Desk Insights
Best Use Case: This cable is the right solution when your Furuno GPS antenna’s standard cable doesn’t reach the helm — typically on vessels 40 feet and larger where the antenna is mounted on a mast or hardtop well above and aft of the helm station. Before ordering, measure your actual cable routing path (not straight-line distance) from the antenna mount to the chartplotter connection point, including any bends around hatches, through cable runs, and down to the helm. The 25-metre length suits most larger vessel installations, but confirm the 7-pin connector type matches your specific Furuno antenna and chartplotter model before ordering — Furuno uses different connector types across their product range.
Installation Note: Route cable away from high-voltage wiring and RF sources where possible. Secure all connections and use cable ties or conduit to protect the cable run from chafe and UV exposure.
Estimated Packaging: Coiled cable box approximately 12" × 12" × 4" (30 × 30 × 10 cm), approx. 1 kg shipped.
