I’ll second that.  RF is witchcraft.

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.

Trees were eating up multi path that is now harming your signal.

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?
