What should you do for safety if you put up a UHF transmitting antenna?
D
Answer
Basic radio theory
Type
A
Make sure the antenna is near the ground to keep its RF energy pointing in the correct direction
B
Make sure you connect an RF leakage filter at the antenna feed point
C
Make sure that RF field screens are in place
D
Make sure the antenna will be in a place where no one can get near it when you are transmitting
Answer Notes
The most effective way to protect people from hazardous Radio Frequency (RF) exposure is by maintaining a safe physical distance. Because RF energy dissipates rapidly as you move further away from the radiating source, placing a UHF antenna out of reach ensures that no one absorbs harmful levels of RF radiation.
Placing an antenna near the ground actually increases the risk of human exposure, making it a dangerous choice. Options mentioning RF leakage filters or field screens are distractors that sound technical but are not standard safety practices for amateur antenna installations.
