Effective radiated power refers to how far away from the source a signal can be received and interpreted. The ________ the frequency, the ________ the effective radiated power.
A) lower; lower
B) lower; higher
C) higher; lower
D) higher; higher

Question

Quizplus · Accepted Answer

Effective radiated power is not directly about how far a signal can travel, but rather the power radiated by a transmitter antenna as compared to the power radiated by a hypothetical isotropic antenna. However, lower frequencies tend to have better propagation characteristics, allowing signals to travel further and penetrate obstacles more effectively. This doesn't mean the effective radiated power is inherently higher with lower frequencies, but in practical terms, lower frequencies can be advantageous for long-distance communication. The statement as phrased might be misleading, but based on common interpretations and the options provided, B is the closest to a correct answer, assuming it's discussing the practical implications of frequency on signal propagation and not the technical definition of effective radiated power.
