I suspect you actually need the foliage to scatter more signal your way, especially if there is something more than just the trees blocking the path.
Also, in the very rare circumstances I have shot 5 GHz through trees, I have noticed that it is affected by wind blowing the branches around. You might have better success with a lower frequency. The fact that the trees are only 1/10 mile from one end is of course not optimal. Any reason you need to be 40 feet up at the house? You say urban area, is this to get over other buildings? If not, like others have said, experiment with going lower to see if it’s multipath off the ground when the leaves are gone. Although such experiments are easier with equipment that has tone alignment. Maybe a UBNT bargraph would be good enough.
