Line of Sight Calculator
This line of sight calculator calculates how far the horizon is from an antenna placed at a particular height. The calculators also calculates the radio horizon. It assumes there is nothing between the radio signals and the antenna horizon. To get maximum line of distance you need to enter the height of the antenna.
Calculate the Line of Sight & Radio Horizon
Where,
h = height of the antenna
R = radius of the earth
dl = total line of sight
dr = radio horizon (actual service range)
