Line of Sight Calculator. This CalcTown 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 ... Your line of sight is the visible path of travel from your vehicle to the target area. This line can be blocked by a curve, the crest of a hill, a wooded If you cannot see around an obstruction, you must slow down and be ready to alter your position until you can reestablish a clear line of sight to your...

*Substitute the above given values of Station1 and Station2 in the formula, = √ (2*height) = √ (2*250) = 22 Miles . = √ (2*height) = √ (2*350) = 26 Miles . Line of Sight = 22 + 26 = 48 Miles.
