What about leaving the re bar cage alone, and installing a dedicated
ground conductor within the foundation which would be connected to the
tower itself above the foundation and would be laid within the
foundation a few inches from the exterior? If the conductor were
something like galvanized steel strap, there would be little potential
for electrolysis with the rebar and j bolts. Any comments???
