Improves performance of electronics and reduces RF interference. Offers the best path for hull bonding without long runs of copper foil. Deters severe electrolysis and galvanic corrosion problems. Sintered porous bronze spheres for maximum conductivity in a compact size. Low drag, non-fouling shape scrapes clean with a wire brush. Easy 2-step hull installation. Includes one gold plated mounting bolt and silver contact paste. Note: due to its short length, the Dynaplate does not make an adequate single sideband counterpoise.
