I need three ground rods, The copper ones are easy to get here. Over the years I have had several different brands of chargers.Doesn't seem to make a difference. I am only running about 4000 feet of fence though. Poor grounding will make fellow chase lot of ghost trying to figure out the problem.
I saw an article a few years back about putting a flourescent light tube on the fence to see if it is always working. I forget now though if it was in paralell or series
