Directional antennas with good shields, might be another option. Rory

Most of the time I see improvements by lowering the height on the side that's suspected of getting the multipath. � On Wed, Dec 23, 2015 at 1:10 PM, Chuck McCown <[email protected]<mailto:[email protected]>> wrote: 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.� � From: Josh Luthman<mailto:[email protected]> Sent: Wednesday, December 23, 2015 11:05 AM To: [email protected]<mailto:[email protected]> Subject: Re: [AFMUG] NLOS, 5ghz, Foliage, and Rain � 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. � � Josh Luthman Office: 937-552-2340<tel:937-552-2340> Direct: 937-552-2343<tel:937-552-2343> 1100 Wayne St Suite 1337 Troy, OH 45373 � On Wed, Dec 23, 2015 at 1:02 PM, Nate Burke <[email protected]<mailto:[email protected]>> wrote: 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.

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.
