Nate,
Chuck is right. How high are the radios on each end of the link?
Sometimes you can get around multipath issues by changing the radio
heights. Most of the time I see improvements by lowering the height
on the side that's suspected of getting the multipath.

Used to be that folks that used my superstingers reported better
multipath resistance than yagis at 900 MHz. I think that a
larger capture area may have something to do with it.

Powerbridge has a wider beamwidth and picks up from "around the
trees". I've seen this only at a customer site with a Beam vs
Nanostation. Roughly the same signal but the Beam was absolutely
worthless compared to the Nanostation.

Is it inherent to the spectrum, or will different radios cope
with it differently? I think I remember that being one of
the claims to fame of the PTP600, was that it handled
multipath better.

Subject: [AFMUG] NLOS, 5ghz, Foliage, and Rain
I have a PTP NLOS link which is working the opposite of
what I expect, and I'm having trouble understanding it.
It is a NLOS link in 5ghz (2.5 mile link, Urban area,
<1/8 Mile is NLOS). 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?
