Have a 4.4 mile link with major trees at 30 yards and 300yards, clear the rest of the way. Had the closest trees topped by 20 feet ($200) to get a clearer LOS, and by good fortune the neighbor topped his trees ($300) to clear the way at 300 yards. The end result was no perceptable improvement in the wap11 v2.2 wireless link with 24db dishes at each end.
