For some reason when I did my ground radials a few years ago I remember using 00 bare copper stranded wire leading out from my tower to several cadwelded ground rods and also to the SPG bulkhead at the shack. Now I see everyone talking about using #4 and #6 gauge solid wire. I'm getting ready to do my new tower's ground system. What size ground radial wire should I use? 73, David, K4ZZR
