Struggling with pesky radio frequency interference (RFI) that disrupts your marine electronics or VHF communications? The Newmar SCREEN-25 Copper Screen steps in as a reliable solution, delivering superior shielding through its precision-engineered copper mesh. Boat owners and electronics enthusiasts swear by this material for crafting effective ground planes right in the hull, ensuring crystal-clear signals and uninterrupted performance on the water.

Precision Mesh for Unmatched Shielding

Crafted from high-purity copper, this screen features an ultra-tight weave with 0.05" x 0.01" wire spacing. That fine grid blocks electromagnetic interference (EMI) across a broad spectrum, from HF to UHF bands commonly plaguing marine setups. At 25 feet long and 4 feet wide, it provides ample coverage for most vessel applications without unnecessary waste.

• Exceptional Conductivity: Copper's natural properties create low-resistance paths for currents, minimizing noise and enhancing antenna efficiency.
• Durability in Harsh Environments: Resists corrosion better than alternatives when properly installed, standing up to saltwater exposure and vibrations.
• Flexible Installation: Easily conforms to curved hull surfaces or folds neatly into enclosures for targeted RF barriers.

Versatile Applications Beyond the Basics

While perfect for establishing a ground plane in fiberglass hulls—simply bond it to the interior and connect to your grounding system—this copper screen shines in other scenarios too. Slip it inside electronics boxes to shield sensitive circuits from external noise, or layer it in custom RF compartments for ham radio setups on board. Anglers targeting fish finders and navigators have reported fewer dropouts after integrating it strategically.

Pro Tip for Hull Grounding

Prep the surface with a marine-grade epoxy for adhesion, then solder or clamp leads to bulkhead grounds. Test with a multimeter for continuity—aim for under 0.1 ohms across the plane. This setup can slash SWR readings dramatically, boosting your radio's range.

Why It Outperforms Standard Shielding Options

Unlike aluminum foils that oxidize quickly or coarser meshes that leak high frequencies, this copper screen maintains integrity over seasons of use. Its density rivals commercial Faraday cages but rolls out flat for DIY projects. Marine electricians appreciate how it integrates seamlessly with bonding systems, preventing stray currents that lead to electrolysis issues.

Real-world feedback highlights reductions in alternator whine and inverter noise—common culprits in off-grid boating. Pair it with proper coax routing for a noise-free electrical ecosystem.
