What is a proper grounding method for a tower?

Use separate eight-foot rods at each leg, bonded together and to the tower.

Start playing free

  1. Bonded eight-foot rods at each tower leg ✔
  2. One four-foot rod at the base
  3. A ferrite choke between tower and ground

Why: Ground rods at every tower leg spread the grounding path around the structure. Bonding the rods and tower together creates one connected grounding system.

Huh, didn't know that: Bonding helps keep grounded parts at similar electrical potential.

The dad joke
The ground rods bonded because teamwork kept them grounded.
