A system for suppressing the effects of lightning including an antenna, a cable extending from the antenna, an enclosure having an interior volume, a coil of conductive wire received within the interior volume of the enclosure, and a piece of electronic equipment suitable for receiving from or transmitting through the antenna. The electronic equipment is interconnected to a lead from the coil of conductive wire. The coil of conductive wire has another lead connected to the cable. The cable is a coaxial cable or a heliaxial cable. A conductive grit or steel shot fills a portion of the interior volume of the enclosure around the coil of conductive wire. A grounding rod is electrically interconnected to at least one of the cables, the enclosure and the electronic equipment.
