Glazed Ceramic Center/End InsulatorThe -16C06 is a six-pack of dog bone ceramic glazed center or end insulators. It will not break with long antennas and will not arc over or melt even under full legal power. Molded ridges give an extra long path to prevent high voltage breakdown. Smooth wire holes prevent wire damage. The 16C06s can be used as a center or end insulators for diples, doublets, G5VRs, guy wire, or vees.
