What should you do for safety if you put up a UHF transmitting antenna?
- AMake sure that RF field screens are in place
- BMake sure the antenna will be in a place where no one can get near it when you are transmitting
- CMake sure the antenna is near the ground to keep its RF energy pointing in the correct direction
- DMake sure you connect an RF leakage filter at the antenna feed point
Correct answer: B — Make sure the antenna will be in a place where no one can get near it when you are transmitting. From the official ISED question bank, verified word for word.
