Made from sintered porous bronze spheres, heat- and pressure-bonded, it provides maximum conductivity in a compact 457 mm long, 152 mm wide, and 13 mm thick format, weighing 5 kg. Its low-drag, non-fouling design minimizes impact on vessel performance.\n\u003c\/p\u003e\n\n\u003ch3\u003eElectronic Performance and Protection\u003c\/h3\u003e\n\u003cp\u003e\n    This Dynaplate improves the performance of onboard electronic equipment while significantly reducing RF interference. It provides an optimal path for hull bonding, eliminating the need for long copper strips. Ideal for electrical bonding systems and RF applications, it acts as a sacrificial metal after zinc anodes to protect stainless steel components from electrolysis and galvanic corrosion. The \u003cstrong\u003eMarinco 4018\u003c\/strong\u003e plate is specifically suited for SSB (single sideband) and AM radio transmitters, offering the necessary \"counterpoise\" (a large solid surface in the water) for optimal operation. It also provides enhanced lightning protection by offering a direct, low-resistance path to dissipate strikes, reducing the risk of hull damage and electric shocks.\n\u003c\/p\u003e\n\n\u003ch3\u003eInstallation and Compliance\u003c\/h3\u003e\n\u003cp\u003e\n    Installing the \u003cstrong\u003eMarinco SUPER DYNAPLATE 18 X 6 X 1\/2\"\u003c\/strong\u003e grounding plate requires a 9 mm (3\/8\") drill bit and a 9\/16\" wrench. Mounting hole spacing is 250.8 mm (9-7\/8\") center-to-center horizontally and 76.2 mm (3.0\") top to bottom. Included mounting hardware includes a 3-inch gold-plated bolt, three 3-inch bronze bolts, bronze mounting nuts, and copper washers. Compliant with ABYC (American Boat \u0026 Yacht Council) standards, this Dynaplate must always be mounted in a location that remains submerged and must not be painted. Electrical connections must be made only to the gold-plated bolt. Maintenance is limited to regular cleaning with a wire brush. This product provides a grounding surface equivalent to 9.3 square meters (100 square feet) of copper sheet.\n\u003c\/p\u003e\n\u003cp\u003e\n    Warning: This product is subject to a California Proposition 65 warning due to the presence of chemicals, including di(2-ethylhexyl)phthalate (DEHP), known to cause cancer, birth defects, or other reproductive harm.\n\u003c\/p\u003e","brand":"Marinco","offers":[{"title":"Default Title","offer_id":56137070313812,"sku":"4018","price":803.54,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0988\/3274\/4788\/files\/family-6152SPP-4018-1.jpg?v=1781650335","url":"https:\/\/skysat.fr\/en-gb\/products\/marinco-super-dynaplate-marine-grounding-plate","provider":"Skysat","version":"1.0","type":"link"}
