Why should you make sure that no one can touch an open-wire transmission line while you are transmitting with it?
- A Because contact might cause spurious emissions
- B Because contact might cause a short circuit and damage the transmitter
- C Because high-voltage radio energy might burn the person
- D Because contact might break the transmission line
Correct answer: C — Because high-voltage radio energy might burn the person. From the official ISED question bank, verified word for word.
Why
When you transmit, an open-wire line carries strong radio frequency energy that acts like high voltage. The full explanation — and one for every question — is in Pro.
