Technician exam question T0C04
Subelement T0, SAFETY· Group T0C
What factors affect the RF exposure of people near an amateur station antenna?
- A.Frequency and power level of the RF field
- B.Distance from the antenna to a person
- C.Radiation pattern of the antenna
- D.All these choices are correct (correct answer)
WhyThe frequency and power level of the RF field, distance from the antenna to a person, and the antenna's radiation pattern all affect RF exposure near an amateur station antenna. How much RF exposure a person near an antenna receives depends on the frequency and power of the field, how far away they are, and the antenna's radiation pattern (whether it's aimed toward or away from them), so all three factor in, answer D. Picking just one of A, B, or C would ignore the other variables that genuinely affect real-world exposure.
