Grounding the tower at 3 ft or so above the concrete base and away from the
base abt 6 ft is fine. I used OO wire to ground rods. Old, used, welding
wire is great for this purpose.
I would never ever ground the re bar or anything in the concrete. I have
seen 2 tower bases that had taken an indirect lighting hit though the
ground. The water boiled in the concrete from the heat and exploded the
concrete bases. One other base was within 100 ft of the others and was not
grounded and it was fine.
