Nate, can you get enough bandwidth through a 10MHz 2.4GHz signal? Rory

Most of the time I see improvements by lowering the height on the side that's suspected of getting the multipath.

UBNT, 2' dish to a Powerbridge.� Here's the part I can't figure out.� Over the summer, when the trees are leafed in, the link is rock solid, no signal change, No modulation change. Rain, Shine, Night, Day, stays exactly the same.� However, over the winter, when there are no leaves, it loses signal, and the signal and modulation fluctuate dramatically. Rain will drop the link out.� I have tried re-alignment after the foliage has dropped off, and was not able to gain signal, or change the pattern at all.� I'm guessing it must be some sort of Multi-path/reflection that the foliage is blocking. Would a different radio handle this better than the UBNT?� Like if I changed it to EPMP, AF5x, or PTP600 would it act differently?� Or is there something else at play that I haven't thought of? �
