8 feet is required for building codes to protect houses from lightning. Electric fences are less likely to be hit by lightning so I think multiple shorter grounding rods, spread out along the fence line, would be better. But I could not find any information about this anywhere.
That's what I have right now. But If I expand the fenced area, I should spread out the ground rods more. Right?
I don't have a perpetually wet area like you do, but I want to make one with some shade trees. I use a solar charger (Parmak) so that means the charger will be in a dry, sunny, area...
For big fenced areas (an acre or more), where should grounding rods go? Should I space them out around the perimeter, or keep them close to the fence charger? All the diagrams I see from electric fence manufacturers just have 3 rods next to the fence charger, but I don't see how that will...
