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.
