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.
