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.
