Enhance your marine navigation setup with the reliable 20m cable designed specifically for Simrad HALO Dome Radar and Nemesis systems. This extension cable delivers seamless connectivity, allowing you to position your radar dome exactly where it performs best—far from the helm or processor unit—without compromising signal quality or reliability on the water.

Why This Cable Makes a Difference for Your Vessel

Marine environments demand rugged, dependable components. Crafted to withstand harsh saltwater exposure, constant vibrations, and temperature swings, this 20-meter (65.6 feet) cable ensures your HALO Dome Radar or Nemesis operates at peak performance. Unlike shorter stock cables, it provides the flexibility to route wiring through bulkheads, around decks, or along masts, simplifying complex installations on larger boats or yachts.

• Superior Signal Integrity: Shielded construction minimizes interference from engines, radios, or other electronics, preserving the radar's 360-degree, real-time pulse compression scanning.
• Plug-and-Play Convenience: Features secure, weatherproof connectors that match Simrad's proprietary interfaces, reducing setup time and eliminating the need for custom adapters.
• Extended Reach Without Compromise: At 20 meters, it supports installations where space is at a premium, like flybridge setups or multi-station bridges, while maintaining low latency for instant target detection.
• Durability Built for Boating: UV-resistant jacket and tinned copper conductors resist corrosion, ensuring years of trouble-free service even in relentless offshore conditions.

Perfect Compatibility Across Simrad Ecosystems

This cable integrates effortlessly with HALO Dome Radar models, including HALO20, HALO20+ and their Nemesis variants, as well as compatible Simrad multifunction displays like NSO evo3 or NSS evo3 series. It's an essential upgrade for boaters expanding their Simrad network, pairing radar data with chartplotters, autopilots, and sonar for a unified command center.

Whether retrofitting an older HALO installation or building a new electronics suite, this cable bridges the gap between dome and processor, supporting high-resolution imaging for bird detection, collision avoidance, and navigation in fog or clutter-heavy waters.

Installation Tips for Optimal Performance

Getting the most from your radar starts with smart cabling. Route the cable away from high-power sources and use cable ties or conduit for protection. Pre-terminate connections on deck to avoid splicing, and test continuity before finalizing the run. For best results:

1. Plan your route to minimize sharp bends—aim for gentle curves under 90 degrees.
2. Secure it with non-corrosive clamps every 1-2 meters to prevent chafing.
3. Pair with Simrad's recommended power cables for balanced electrical loads.
4. After installation, run a full 360-degree sweep calibration via your MFD to verify coverage.

Pro tip: In high-vibration areas like near stabilizers, add strain relief at entry points to extend cable life.

Real-World Benefits for Serious Boaters

Anglers chasing offshore pelagics appreciate the extended range for dome placement high on the tuna tower, spotting birds from afar. Cruisers value the clutter-free helm wiring, while commercial operators rely on its robustness for 24/7 operations. This isn't just a cable—it's the backbone of safer, smarter boating.
