(Last Update: 10/05/2006)

Calculation LOS distance: (LOS = Loss Of Signal)

Rule-of-thumb method:

Multiply your height in ft by 1.5, the take the square-root of that number & this value is the approximate distance in miles your signal will go to the horizon. (The actual distance is a bit further due to reflections & refraction.)

D(mi) = sqrt(Height(ft) * 1.5)
