CWNA ch 4 5 6 QUESTIONS AND ANSWERS GRADED A+ Antennas play a vital role in receiving signals, but no role in transmitting False The FCC places no limits on the amount of power that can be generated by an IR. False Low-gain antennas have a shorter range than high-gain antennas but do not have to be precisely aimed. True The strength of a signal from an omnidirectional antenna flows out 90 degrees from the antenna's orientation. t or f True Highly-directional ant...
