Why is it best to use galvanized grounding rods instead of just driving a large copper pole into the ground since copper is a good conductor?
Bare metals driven into the ground, regardless of their conductivity, are susceptible to oxidation and/or rust. Because power fence chargers / energizers emit only a brief, powerful jolt, it is very important that the conductivity of ground rods be maximized to insure that the animal receives a good shock.
