Tropospheric ducting may be an overstatement. I am trying to calculate the angle of refraction when the beam passes through a temperature inversion. I have a 5 mile link that has a ridge-top end-point 1200 feet above it other end-point on the vally floor. If the effect is large enough, I want to set up a second pair of 24dBi antennas and use antenna diversity.
