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 midpoint 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 midpoint), the 60% (no obstacle) radius and the height of the earth curvature at the midpoint
of the Total link distance.
