This design features a choke coil and a lightning arrestor combination which is the two essential components of an effective lightning diverter. The choke coil is slows the surge of electrical energy by inductive forces created in the coil. When lightning strikes, the pool of energy searching for the ground jumps the gap in the arrestor and finds the fastest route to the ground. The arrestor features an adjustable gap. To use it properly, set the gap to the smallest distance possible without the charger causing an arc in the gap by itself. To be effective the ground must be as good as the one on your charger. Install the lightning diverter as close as possible to your fence energizer.
