Where the hell did this guy work in Florida? We did a bunch of radio equipment shelters on the interstate and one in every prison. These things got the regular Ufer on the buildings and the tower base, bonded to a ground ring in 1/0 and 40' rods on the corners of the ring and radials going out from there. All of this got tied to a big copper plate in the building that was the ground electrode for everything. Single point ground, and very effective.
