Why is line-of-sight important in radio communication?

Line-of-sight is crucial in radio communication because obstacles such as buildings, trees, and hills can obstruct radio waves, which can significantly limit the effective range of communication. When there is a clear line-of-sight between the transmitter and receiver, the signal can travel unimpeded, providing a stronger and more reliable communication link. If the line-of-sight is obstructed, the signal may weaken, become distorted, or even fail entirely, making it difficult or impossible for the intended communication to occur. This principle underscores the importance of clear visual paths in radio transmission, particularly for frequencies that are more susceptible to such interference, thereby ensuring effective communication within the desired range.
