Freshnel Zone Calculator
Enter the Total link distance (in Miles or Kilometers). If you do not enter an Obstacle distance (in Miles or Kilometers) this calculator will use the mid-point for all calculations (Note: assumes antennas at same height). Enter the system Frequency in MHz and then click the 'Calculate' button. (1 GHz = 1000 MHz e.g. 2400 = 2.4 GHz) The calculator will generate the radius of the 1st Fresnel zone only (at the obstacle point or the mid-point), the 60% (no obstacle) radius and the height of the earth curvature at the mid-point of the Total link distance.
