Line-Of-Sight

To use the calculator you need to enter any two of three values and the calculator will compute the third one (if it is mathematically possible). For example: you can enter the desired distance between antennas (L) and the height of one of the antennas (h1 or h2) (don't forget to select proper units), select the unit for the result and click the [Compute] button which is connected to an unfilled field.

h1 =


h2 =
