Newmar 18E Ground Plate 18 X 6 X 1/2 100 SQ FT

The Newmar 18E Ground Plate 18 X 6 X 1/2 is a specialized RF (radio frequency) ground system designed for vessels, RVs, and mobile command platforms that require clean, noise-free electrical grounding. Built for tactical communications operators, maritime professionals, and field teams who depend on reliable signal integrity, this ground plate eliminates RF noise that compromises radio transmission clarity and reception. The 100 square foot equivalent contact area makes it an industrial-grade solution for applications where standard grounding methods introduce interference or signal degradation—critical in law enforcement, military, and emergency response communications.

The Newmar 18E achieves superior grounding performance through porous copper construction that dramatically magnifies contact area and establishes direct water-hull interface for maximum conductivity. Unlike conventional flat plates, the porous matrix design increases surface contact exponentially, reducing impedance and providing an excellent low-resistance path to ground. Silicon bronze hardware is included for corrosion resistance in saltwater and humid environments, ensuring long-term reliability without oxidation or connection degradation. This design creates a true RF ground rather than a lightning ground—optimized specifically for radio frequency suppression rather than lightning strike protection, making it ideal for continuous communications use where noise floor matters.

Tactical teams, vessel operators, and mobile command centers benefit most from the Newmar 18E when integrating HF/VHF radio systems, satellite communications, or sensitive electronic warfare equipment. Installation requires direct contact between the plate and seawater or conductive external surface; the 18 X 6 X 1/2 inch form factor fits most hull configurations and equipment mounting bays. This ground plate is essential for field operations, offshore patrol vessels, emergency management trailers, and any platform where RF noise must be minimized to preserve signal fidelity. Weight of 12 lbs makes it practical for deployment without structural penalty, while the porous copper matrix ensures performance consistency across extended operational cycles.
