The height of a VHF radio antenna is more important than the power output wattage of the radio because __________.

Correct Answer: Option A — VHF communications are basically "line of sight"

VHF communications operate at very high frequencies that travel via direct line-of-sight. Because radio waves are blocked by the earth's curvature, elevating the antenna height directly extends the horizon distance, proving more critical than transmitter wattage.
