I hope that you have had better luck with the Cambium 90 degree 5GHz antenna. Panel antennas naturally have a Sin(x)/x characteristic giving nulls. The Cambium antenna has had these lower nulls substantially removed and for normal deployments is intended to give a constant signal from -30degrees out to the peak of beam if that is pointed at 5km. This characteristic is fully modelled in LINKPlanner.
