Technician exam question T0C08
Subelement T0, SAFETY· Group T0C
Which of the following actions can reduce exposure to RF radiation?
- A.Relocate antennas (correct answer)
- B.Relocate the transmitter
- C.Increase the duty cycle
- D.All these choices are correct
WhyRelocating antennas can reduce exposure to RF radiation. Moving an antenna farther from occupied areas or higher up directly reduces the RF field strength people are exposed to at ground level, answer A. Relocating the transmitter itself (B) doesn't change the field radiated from the antenna, which is what actually matters for exposure, and increasing duty cycle (C) raises average exposure rather than reducing it, so D, which depends on both of those also being valid ways to cut exposure, is also wrong.
