Neighbor installed an Ham Radio antenna disguised as a flag pole. He used it before installing some type of equipment that induced a stray voltage into the ground. At least 14 homes around him tripped AFCI breakers, except for the one home that had installed his own driven ground. The homes closest to the antenna tripped the most breakers. The home with the driven ground was the 2nd closes to the antenna. It appears to me the driven ground was effective! We have no problem with neighbor and the flag pole looks like any other flag pole. With the homes being struck by lighting and the resulting house fires I will spend about $30 and install an extra ground.
