The huge current spike caused by lightning strikes can induce a harmful voltage surge on all metallic line nearby, including the cables used in a communication system. The lightning protector developed by Micon features a high speed gas discharge tube that can safely channel away harmful voltage surges occurred during thunder storms. The gas discharge tube, whose cost is a fraction of the cost of lightning protector, can be replaced easily and take the hits of lightning surges to protect other costly equipments in a system.
