Abstract
A lightning suppression system including a first wire, a second wire, a third wire, a fourth wire, an enclosure having an interior volume, a first coil connected to the first wire and positioned within the enclosure, a second coil connected to the second wire and positioned within the enclosure, a third coil connected to the third wire and positioned within the enclosure, a fourth coil connected to the fourth wire and positioned within the enclosure, and a piece of electronic equipment interconnected to each of the coils. A conductive grit, such as steel shot, fills a portion of the enclosure around the respective coils. The lightning suppression system is for interconnection to a first twisted pair of wires and a second twisted pair of wires associated with a T1 circuit or a DSL circuit.
