Skywave propagation differs from which type, where waves travel in a straight line?
ASkip propagation
BLine-of-sight travel
CIonospheric refraction
DMulti-hop propagation
Answer & Solution
Correct answer: B. Line-of-sight travel
Line-of-sight waves go straight between antennas, while skywaves are bent back by the ionosphere.
