Technician exam question T0C09
Subelement T0, SAFETY· Group T0C
How can you make sure your station stays in compliance with RF safety regulations?
- A.By informing the FCC of any changes made in your station
- B.By re-evaluating the station whenever an item in the transmitter or antenna system is changed (correct answer)
- C.By making sure your antennas have low SWR
- D.By using only Underwriter Laboratories approved transmitting equipment
WhyYou can keep your station in compliance with RF safety regulations by re-evaluating it whenever an item in the transmitter or antenna system is changed. RF exposure depends on the specific combination of power, frequency, antenna, and geometry in use, so a station needs to be re-evaluated any time one of those elements, the transmitter, the antenna, or its placement, changes, answer B. Notifying the FCC (A) isn't how exposure compliance is maintained, a low SWR (C) affects efficiency but doesn't guarantee safe exposure levels on its own, and UL approval (D) covers electrical safety of the equipment itself, not RF exposure to nearby people.
