Which is a proper grounding method for a tower?

• A. Using a single ground rod for the entire tower
• B. Separate eight-foot ground rods for each tower leg, bonded to the tower and each other
• C. Connecting to a nearby water pipe
• D. Reducing the length of ground rods to save space

Answer: (B)

Using separate eight-foot ground rods for each tower leg, bonded to the tower and each other, is the correct answer because this method ensures a more effective grounding system that can handle the electrical demands and possible lightning strikes associated with a tower structure. This approach allows for a lower impedance ground system, which improves safety by providing multiple pathways for electricity to dissipate into the earth during surges. Each leg of the tower, when independently grounded, increases the tower's overall grounding effectiveness and reduces the risk of uneven grounding, which could create potential hazards. Bonding the ground rods together ensures that all parts of the system remain at the same electrical potential, minimizing the risk of electric shocks or damage to connected equipment. In contrast, a single ground rod for the entire tower could provide insufficient grounding, especially during severe weather or electrical surges. Connecting to a nearby water pipe can be unreliable due to corrosion or interruption in the water supply, while reducing the length of ground rods simply compromises the effectiveness of the grounding system altogether. Proper grounding is vital for both safety and the integrity of radio equipment.
