Summary

Line-of-Sight Formulas Earth’s Curvature Approximately 8 inches (7.98) per Mile Visual Line-of-Sight Approximate distance in miles = 1.33 x √ (height in feet) Radio Line-of-Sight D = √(2Hr) + √(2Ht) Where: D = approximate distance (range) to radio horizon in miles Hr = height of receive antenna in feet Ht = height of transmit antenna in feet These are rough estimates that only consider the curvature of the earth, which does not take into account power, antenna type, antenna gain, frequency, clutter, terrain or other obstructions
