Super Dynaplate f/SSB Radio - 18 x 6 x 1/2Create a proper bonding and grounding system using Dynaplate grounding shoes to reduce the risk of serious hull damage and electrical shock associated with boat lightning strikes by providing a direct, controlled high-capacity path for lightning dissipation. SSB and AM radio transmitters rely upon a proper size ground to operate to their designed capacity. A Dynaplate grounding shoe helps provide a large solid surface (the water surrounding the boat) to push off from. This is technically known as counterpoise and is the other necessary half of the antenna system. The bronze Dynaplate material also serves as the next sacrificial metal on the galvanic scale after the zincs, providing another buffer against corrosion of stainless steel parts.Features:Easy to clean with wire brushConforms to ABYC standardsMounting hardware includedGold plated mounting boltBronze mounting nutsCopper washersWARNING: This product can expose you to chemicals including di(2-ethylhexyl)phthalate (dehp) which is known to the State of California to cause cancer, birth defects or other reproductive harm.
