Newmar GS-2-25 Ground Strap 25'L X 2W

Enhance Your Marine Electronics with Reliable RF Grounding

When you're out on the water, clear communication can make all the difference. Static noise, interference, and unreliable signals from your SSB radio or transceiver can turn a simple call into a frustrating ordeal. That's where a high-quality ground strap steps in, creating a solid path for RF energy to dissipate safely and effectively. Crafted from pure copper for unbeatable conductivity, this flexible strap conforms effortlessly to your vessel's curves, ensuring a seamless installation without compromising performance.

Unlike rigid grounding solutions that crack under vibration or struggle with boat contours, this strap bends and twists to fit tight spaces around antennas, thru-hulls, or engine blocks. At just 0.01 inches thick, it's lightweight yet robust enough to handle the demands of marine environments, where saltwater corrosion and constant motion test every component.

Key Features That Stand Out in Harsh Marine Conditions

• Superior Conductivity: Copper construction provides low-resistance grounding, minimizing RF feedback and noise in sensitive electronics like single sideband (SSB) radios.
• Unmatched Flexibility: Easily shapes to irregular surfaces, from hull fittings to mast bases, for a custom fit every time.
• Generous Dimensions: 25 feet long and 2 inches wide, offering ample length for complex routing while maintaining a broad contact area for optimal current flow.
• Durable Build: Thin profile resists fatigue from boat flexing, ensuring long-term reliability without adding unnecessary weight.
• Versatile Applications: Perfect for bonding metal components to prevent galvanic corrosion or grounding high-power transceivers.

Boat owners rave about how this strap transforms fuzzy transmissions into crystal-clear conversations, especially during long offshore passages when every watt counts.

Real-World Applications for Boaters and Yacht Enthusiasts

Whether you're retrofitting an older vessel or fine-tuning a high-end cruiser, this ground strap tackles common marine electrical headaches head-on. Use it to:

• Ground SSB antennas and reduce RF interference that plagues HF radios.
• Bond thru-hulls, shafts, and rudders to your boat's grounding plate, slashing electrolysis risks.
• Connect engine blocks to battery negatives, stabilizing alternator output and preventing alternator whine in audio systems.
• Link multiple ground points for a unified system, boosting overall electrical safety and performance.

In noisy environments like crowded anchorages or near coastal radars, proper grounding like this keeps your nav gear and comms sharp. It's not just a wire—it's your first line of defense against electrical gremlins that could leave you offline when you need it most.

Installation Tips for Maximum Performance

Getting the most from your ground strap doesn't require a marine electrician. Start by cleaning all contact surfaces with a Scotch-Brite pad and isopropyl alcohol to remove oxidation—copper thrives on skin-to-metal connections. Use ring terminals or stainless steel clamps sized for the 2-inch width, torqued just right to avoid crushing the braid.

Route the strap away from high-heat areas and sharp edges, securing it with UV-resistant cable ties every 18 inches. For best results, pair it with a dedicated dynaplate or copper grounding plate submerged in the bilge. Test your setup with a multimeter for continuity under 0.1 ohms, and monitor for hot spots during transmit. Pro tip: In lightning-prone areas, extend it to a dedicated strike plate for added protection.

This straightforward process pays dividends in clearer signals and safer electrics, often in under an hour.

Why Copper Beats Alternatives for Marine Grounding

Copper's 100% conductivity rating crushes aluminum or steel options, which introduce resistance and heat up under load. Tinned surfaces (common in quality marine straps) fend off verdigris in salty air, while the flat braid design spreads current evenly—reducing I²R losses that rob your radio of power.

Compared to coiled wire or solid bars, this strap's flexibility prevents work-hardening and breaks from hull flex. It's the go-to for pros installing Icom, Yaesu, or Kenwood rigs, where even millivolts of noise can mask weak signals.
