Question
Where should lightning arrestors be located?
Answer Options
- A) Where the feed lines enter the building
- B) On the antenna, opposite the feed point
- C) In series with each ground lead
- D) At the closest power pole ground electrode
Correct Answer: A
Explanation
Lightning arrestors (or surge protectors) are designed to safely divert the massive voltage and current from a lightning strike or large power surge to the ground system before the energy can travel into the sensitive station equipment.
To be most effective, the arrestor must be placed at the point of maximum protection, which is Where the feed lines enter the building. This ensures that the surge is diverted to the external lightning ground rod before the RF energy enters the structure, protecting the equipment and minimizing the risk of fire.
