Why should you regularly clean and tighten all antenna connectors?
- A To help keep their contact resistance at a minimum
- B To minimize dielectric losses
- C To maintain lightning protection
- D To prevent static electricity buildup
Correct answer: A — To help keep their contact resistance at a minimum. From the official ISED question bank, verified word for word.
Why
Antenna connectors can corrode or loosen over time, creating a barrier that stops electrical current from flowing smoothly. The full explanation — and one for every question — is in Pro.
