[TowerTalk] copper or galvanized ground rods in red SC clay

[Kelly Taylor]

Here's an interesting question: if the concrete base is an effective ground connection, do you get more value by placing the rods a rod length away from the base?

If the idea of separation is to prevent saturation during a strike, isn't the base and rod combo at risk of saturation if the rods are too close to the base?
