Thanks for your comments, rance. and YES:
Regarding lightning: all three legs of the tower are bonded to 8' grounding rods, driven into the ground. They are all tied together with ground wire to create a "ground plane", according to the electrician.
I addition the rebard "cage" within the concrete base is connected to the ground plabe. I left threaded rod and rebar projecting fromm each of the three sides of the concrete base. So I guess this adds to the plane.
I love good grounds. Have not (cross fingers) had a hit.
