Navico 10M Extension Cable f/WM-3 Antenna
Navico 10M Extension Cable f/WM-3 Antenna — Product description
Extend the reach of your WM-3 weather module antenna effortlessly with this precision-engineered 10-meter extension cable. Designed specifically for marine environments, it allows you to position your satellite weather receiver exactly where it performs best—far from obstructions, interference, or crowded helm stations. Whether you're optimizing signal strength on a sportfishing boat or ensuring reliable forecasts during long offshore passages, this cable delivers the flexibility serious mariners demand without compromising data integrity.
Why Choose This Extension Cable for Your WM-3 Setup?
In the demanding world of marine navigation, every inch matters. The WM-3 antenna thrives when mounted high and clear, but deck layouts don't always cooperate. This robust 10m cable bridges that gap, letting you route the connection cleanly through bulkheads, conduits, or along rails. Its durable construction withstands UV exposure, saltwater spray, and constant vibration, ensuring years of reliable service. Mariners report noticeably stronger SiriusXM weather signals after relocation, translating to safer decisions amid shifting storms or fronts.
Key Features Tailored for Marine Reliability
- Generous 10-Meter Length: Provides ample distance to relocate your WM-3 antenna to the ideal spot, like a radar arch or masthead.
- Plug-and-Play Design: Features secure, weatherproof connectors that match the WM-3 module perfectly—no soldering or custom adapters needed.
- Daisy-Chain Capable: Link up to two cables in series for a total of 20 meters, ideal for superyachts or multi-station installs.
- Shielded Construction: Minimizes RF interference from nearby VHF radios, radars, or engines, preserving crystal-clear weather data feeds.
- Compact and Flexible: Slim profile snakes easily through tight spaces without kinking or signal loss.
Installation Tips for Optimal Performance
Getting this cable up and running takes minutes, not hours. Start by powering down your chartplotter or multifunction display (MFD). Disconnect the WM-3 antenna from the module, attach one end of the extension here, then plug the other into the antenna. Secure the cable run with zip ties or clips, avoiding sharp bends (maintain a 4-inch radius minimum). Test the connection by checking weather overlays on your Lowrance, Simrad, or B&G display—strong bars mean success. Pro tip: Mount the antenna with a clear 360-degree sky view for peak SiriusXM reception, and consider grounding nearby metalwork to cut noise.
- Power off all electronics.
- Attach cable to WM-3 module output.

Perfect Compatibility Within the Navico Ecosystem
Engineered by Navico (the powerhouse behind Lowrance, Simrad, and B&G), this cable integrates seamlessly with WM-3-equipped systems. It supports real-time weather radar, sea surface temps, wave heights, and lightning strikes directly on your MFD. No firmware updates or special configurations required—just plug in and plot safer courses. It's a must-have upgrade for anyone running HDS, NSS, NSO, or Zeus series units hungry for extended antenna range.
Frequently Asked Questions
Can I use more than one of these 10m extension cables with my WM-3 antenna?
Yes, you can connect up to two cables together for a maximum 20m extension. Beyond that, signal degradation may occur, so stick to the recommended limit for best performance.
Will this cable affect the signal quality of my WM-3 weather module?
No, its shielded design maintains full signal integrity over the 10m length. Users often see improved reception after relocating the antenna to a better vantage point.
Is this extension cable waterproof for marine use?
Absolutely—it's built with IPX7-rated connectors and UV-resistant jacket to handle spray, submersion, and harsh sun exposure on deck.
What displays work with the WM-3 antenna and this cable?
It pairs perfectly with Navico's Lowrance HDS Live/Gen3, Simrad NSS evo3/NSO evo3, and B&G Zeus3S/ Vulcan systems that support the WM-3 module.
How do I troubleshoot weak signal after installing the cable?
Check connections for tightness, ensure no sharp cable bends, and confirm the antenna has unobstructed sky view. Reroute away from high-power electronics if needed.
Does this cable support SiriusXM weather services?
Yes, it fully supports all SiriusXM features via the WM-3, including animated radar, forecasts, and marine observations—no data loss.
Can I cut or splice this cable for a custom length?
We don't recommend it, as it voids the seal and risks signal issues. Use the daisy-chain option or consult a marine electrician for modifications.
Upgrade your weather awareness today and navigate with confidence. This extension cable isn't just wire—it's the key to unlocking your WM-3's full potential on the water.
