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

Result

  • Line of Sight distance (dl)
    km
  • Radio horizon - Service range (dr)
    km

Where,

h = height of the antenna

R = radius of the earth

dl = total line of sight

dr = radio horizon (actual service range)
