Radio Horizon Calculator
This page of converters and calculators section covers Radio Horizon calculator. The calculator calculates radio horizon distance based on antenna height above the surface of the Earth.
INPUT : 200 ft
OUTPUT: 20.08 miles
Radio Horizon Equation
At the VHF and above, space wave is limited to LOS distances . Hence here radio horizon is the limit of the communication distance. Radio horizon is 60% farther compare to optical horizon. This is due to bending effect of wave in the atmosphere.
Following equation or formula is used for radio horizon calculator. As mentioned radio horizon is the function of antenna height.
