Quizplus · Accepted Answer

The distance beyond which earth's bulge should be considered is 7 miles.
Key Takeaway: When planning for paths longer than seven miles, the curvature of the earth is a factor in path planning. It requires that the antenna be located higher off the ground. The additional antenna height needed can be calculated by the square of the distance between the antennas, divided by 8.
