Fresnel Zone Calculator

Radio frequency line of sight is defined by Fresnel Zones which are ellipse shaped areas between any two radio antennas. This calculator calculates the radius of the Fresnel Zone at its widest point. The distance between the two radio antennas and the frequency of operation are required to compute the radius of the Fresnel Zone.
