product description
The GC-7 grounding clamp was developed for equipotential bonding on 7 mm coax cables such as AIRCELL 7, ECOFLEX 7, etc. This eliminates potential differences (voltages) between the coax cable and the earth potential. Especially during thunderstorms, charging can occur on the antenna or on the coax cable. This charge is removed with the earthing clamp and the connected device is protected. A grounding clamp is not a replacement for lightning protection.
