Which of the following statements is true regarding RF propagation communication?
A)The range of RF transmissions increases with frequency.
B)The range of RF transmissions in unaltered with frequency.
C)RF signals with low signal strength can be used for propagation in short ranges.
D)Due to the distances involved, sunspots do not affect RF communications.

Question

Quizplus · Accepted Answer

The statement that is true regarding RF propagation communication is that RF signals with low signal strength can be used for propagation in short ranges.
Key Takeaway: RF signals with low signal strength can be used for propagation in short ranges. This is partly because of the attenuation that the signal suffers from. At low signal strengths, signal regeneration using repeaters is very expensive.
