- AHigh enough so that no one can touch any part of it from the ground
- BAbove high-voltage electrical lines
- CJust high enough so you can easily reach it for adjustments or repairs
- DAs close to the ground as possible
Correct answer: A — High enough so that no one can touch any part of it from the ground. From the official ISED question bank, verified word for word.
Why
Placing a horizontal wire antenna high enough so that no one can touch any part of it from the ground prevents dangerous electric shocks, since radio frequency energy can cause burns or interfere with medical devices like pacemakers. The full explanation — and one for every question — is in Pro.
