Why should your outside antennas be high enough so that no one can touch them while you are transmitting?
- A Touching the antenna might radiate harmonics
- B Touching the antenna might cause television interference
- C Touching the antenna might cause RF burns
- D Touching the antenna might reflect the signal back to the transmitter and cause damage
Correct answer: C — Touching the antenna might cause RF burns. From the official ISED question bank, verified word for word.
Why
When you transmit, your antenna carries strong radio frequency energy that can heat human tissue instantly, causing painful RF burns if touched. The full explanation — and one for every question — is in Pro.
