Furuno NX3H — High-Field GPS Antenna with 10m Cable
The NX3H is a high-sensitivity GPS and SBAS antenna designed specifically for Furuno NavNet TZtouch and NavNet 3D multifunction display systems. It provides accurate, reliable position data to your Furuno MFD network — ensuring your chartplotter, autopilot, and other networked devices have a consistent, high-quality GPS source.
The high-field antenna design delivers fast satellite acquisition and strong position accuracy even in challenging signal environments. The included 10-metre cable provides ample reach from a mast or hardtop mount to the helm electronics, and the waterproof construction allows installation in fully exposed locations.

Parts Desk Insights
Best Use Case: The NX3H is the correct GPS antenna for Furuno NavNet TZtouch and NavNet 3D multifunction display systems that require an external GPS source — either because the MFD lacks a built-in GPS receiver, or because the internal antenna has a poor sky view from its helm location. It’s the purpose-built antenna for these Furuno systems and ensures full compatibility with the NavNet network architecture. If you’re building or upgrading a Furuno NavNet helm, confirm whether your specific MFD model requires an external antenna or includes one — not all NavNet units ship with a GPS antenna. The 10-metre cable is sufficient for most helm-to-mast runs, but measure your routing path before installation to confirm.
Mounting Note: Mount with a clear, unobstructed sky view. Avoid locations directly below a radar dome or in the shadow of a mast or hardtop structure, as these can degrade GPS signal acquisition.
Estimated Packaging: Box approximately 10" × 8" × 4" (25 × 20 × 10 cm), approx. 0.6 kg shipped.
