You want to install a lightning surge protector on your transmission line, where should it be inserted?
- A Anywhere on the line
- B Outside, as close to earth grounding as possible
- C Close to the antenna
- D Behind the transceiver
Correct answer: B — Outside, as close to earth grounding as possible. From the official ISED question bank, verified word for word.
Why
A lightning surge protector must be placed outside the building, as close to earth grounding as possible, so that a massive electrical strike from a nearby lightning bolt can flow directly into the ground before it ever reaches your home or expensive radio gear.
