Why should you make sure the antenna of a hand-held transceiver is not close to your head when transmitting?
- A To use your body to reflect the signal in one direction
- B To keep static charges from building up
- C To help the antenna radiate energy equally in all directions
- D To reduce your exposure to the radio frequency energy
Correct answer: D — To reduce your exposure to the radio frequency energy. From the official ISED question bank, verified word for word.
Why
When a hand-held transceiver transmits, it sends out radio frequency energy, which is a form of radiation that can heat body tissues if you are too close. The full explanation — and one for every question — is in Pro.
