T0B08 What is considered to be a proper grounding method for a tower?
A. A single four-foot ground rod, driven into the ground no more than 12 inches from the base
B. A ferrite-core RF choke connected between the tower and ground
C. Separate eight-foot long ground rods for each tower leg, bonded to the tower and each other
D. A connection between the tower base and a cold water pipe
- C. Separate eight-foot long ground rods for each tower leg, bonded to the tower and each other
- Don’t confuse a safety ground with an RF ground! A tower’s safety ground is intended to conduct any lightning energy to the earth, reducing the amount traveling along your feed lines. Grounding each leg of the tower balances lightning currents — a weak ground will encourage more energy to flow along your feed lines. It also dissipates the charge into the ground as widely as possible. [Ham Radio License Manual, page 9-12]
