Garmin Fist Microphone Extension Cable - VHF 210/210i & GHS 11/11i - 10M

Extend your control over communications on the water with the Garmin fist microphone extension cable. This rugged 10-meter (33-foot) cable provides the flexibility you need to position your VHF fist microphone exactly where it works best—whether that's at the helm, in a nearby cabin, or across the deck. Designed specifically for marine environments, it connects seamlessly with 12-pin interfaces, ensuring reliable signal transmission without interference or signal loss.

Key Features and Benefits

• Generous 10-Meter Reach: Perfect for larger vessels or custom installations where the radio unit and microphone need to be separated, giving you freedom of movement without compromising performance.
• 12-Pin Precision Connector: Matches Garmin's high standards for secure, weather-resistant connections that stand up to salt spray, vibrations, and constant exposure to the elements.
• Marine-Grade Durability: Built with flexible yet tough cabling that resists UV damage, abrasion, and moisture, making it a long-lasting addition to your boating setup.
• Plug-and-Play Simplicity: No special tools or modifications required—just connect one end to your compatible VHF radio and the other to the fist microphone for instant extended range.

Perfect Compatibility for Seamless Integration

This extension cable works flawlessly with a range of Garmin VHF radios and handsets, including the VHF 210, 210i, 215i, 315i, and GHS 11/11i series. It's an ideal upgrade for boaters who rely on clear, dependable VHF communications for safety, navigation, and coordination. Whether you're outfitting a sailboat, fishing vessel, or yacht, this cable ensures your setup remains tidy and functional, routing neatly through bulkheads or along rails without excess slack.

Why Boaters Choose This Extension Cable

In the demanding world of marine electronics, every inch counts. Short factory cables can limit your options during installation, forcing awkward microphone placements that hinder quick access during critical moments. This 10-meter extension solves that by letting you mount your VHF radio in a protected console while keeping the fist mic within easy reach—perhaps mounted on a bulkhead or pedestal for all crew members. It's especially handy for multi-station setups or when retrofitting older systems. Users report crystal-clear audio transmission even at full length, thanks to Garmin's quality shielding that blocks engine noise and RF interference common on the water.

Installation Tips for Optimal Performance

Getting the most out of your extension starts with smart routing. Secure the cable with marine-grade zip ties or clips to avoid snags, and use cable glands for watertight passes through fiberglass or metal. Test the full length after installation by keying the mic and listening for any dropouts—Garmin's design minimizes this risk. Pair it with a quality VHF antenna for the best overall range, and you're set for safe voyages.
