To top it all off this was built inside a metal garage and the skin of the building is grounded too.Tall , That almost sounds like my Chicken coop ! When I built it I read an article that said " Build it so a Predator Can't get in " So I lined the floor/walls w/ wire mess under the Ply Wood so they can't chew through , it also has a Metal Roof ! I know close but No Cigar ! But I wasn't thinking " Faraday Cage " back then . Now .... You got me thinking ! Where's them Damn Grounding Rods ?
