Bronze grounding plates replace yards of copper foil. Looks like a solid bronze plate, but actually a porous matrix of bronze spheres, presenting the same effective electrical surface as a much larger expanse of copper foil. Use as electronic ground for SSBs, Lorans and ham transceivers, or as a ground reference in bonding systems. Includes gold-plated bronze flathead fasteners and silver contact paste for superior conductivity. Plates have tapered ends and rounded edges for reduced turbulence.
