Newmar GS-2-100 Ground Strap 100'L X 2W

Enhance Your Vessel's Electrical Performance with Premium Copper Grounding

When it comes to keeping your marine electronics crystal clear and interference-free, nothing beats a high-quality copper ground strap. Designed for demanding boating environments, this flexible copper braid excels at conducting RF signals away from sensitive gear like SSB radios and transceivers. Its ultra-thin profile—measuring just 0.01 inches thick—allows it to hug irregular surfaces effortlessly, ensuring a secure, low-resistance path for grounding without the bulk of rigid alternatives.

Boat owners swear by copper braids for their superior conductivity over aluminum or steel options. Copper's natural properties resist corrosion in salty air, maintaining peak performance season after season. Whether you're chasing fish on the open water or cruising coastal routes, reliable grounding means quieter transmissions, stronger signals, and fewer headaches from RF noise.

Key Advantages for Marine Applications

• Exceptional RF Conductivity: Perfect for bonding antennas, thru-hulls, and radios, slashing electromagnetic interference (EMI) that plagues noisy setups.
• Supreme Flexibility: Bends and twists to match your hull's curves, installing neatly in tight spaces like bilges or engine compartments.
• Durability in Harsh Conditions: Tinned copper construction fights oxidation and saltwater exposure, outlasting cheaper braids.
• Versatile Sizing: At 100 feet long and 2 inches wide, it handles extensive grounding runs or multiple connections with ease.
• Low Resistance Path: Minimizes voltage drops, ensuring your electronics operate at full potential even under load.

Common Uses on Board

Integrate this ground strap into your system's backbone for optimal results. Marine pros use it to create a robust ground plane for HF/SSB setups, linking the antenna counterpoise directly to the water. It's also ideal for tying together metallic components like propellers, shafts, and rudders—preventing stray currents that lead to electrolysis.

In liveaboard scenarios, it quiets inverter noise affecting stereos or GPS units. For performance boats, it stabilizes radar and VHF performance during high-speed runs. Think of it as the unsung hero that keeps your comms reliable when you need them most, from offshore races to family outings.

Pro Tips for Installation and Maintenance

Start by cleaning connection points with a marine-grade contact cleaner to remove oxidation. Use ring terminals crimped securely at ends, and apply dielectric grease for corrosion protection. Route the strap away from high-heat sources and chafe points, securing with UV-resistant ties.

Over time, inspect for frays or green patina—snip damaged sections and reconnect promptly. Pairing it with a dedicated DC ground bus bar amplifies effectiveness, creating a star-ground topology that isolates noise sources. Avoid common pitfalls like undersized straps or poor bonds, which amplify rather than eliminate interference.

For best outcomes, test your setup with a multimeter for continuity and an SWR meter for RF performance post-install. This simple step confirms your investment pays off in clearer audio and data.

Why Copper Braid Outshines the Rest

Copper's unmatched thermal and electrical conductivity—about 60% better than alternatives—makes it the gold standard for RF grounding. Braided design increases surface area for skin-effect currents at high frequencies, dropping impedance where solid wire falls short. In marine settings, its malleability prevents cracks from vibration, a frequent failure in stiff competitors.

Users report dramatic noise reductions: one offshore sailor noted 20-30 dB drops in receiver hiss after retrofitting. It's not just about function—it's peace of mind knowing your electronics won't falter mid-voyage.
