	How high do the antennas have to be?

Solution Since the Earth’s surface is curved, antennas must be elevated above the ground if they are to communicate at a significant distance. One formula for estimating required antenna height above level ground is as follows: H = D (squared) / 2 where D = Distance in miles and H = height in feet. So if the distance was 5 miles, 5 squared = 25 which is then divided by 2 to come up with 12.5 feet. The antenna would have to be at least 12.5 feet high from level ground.
