Does anyone have recommendations for outdoor wireless point to point equipment?

Also, how does inclement weather impact this type of technology?

Thanks in advance.

Yes, it does. The impact depends in part on which frequency bands
you are using: 2.4 GHz is worse than 900 MHz.

When you are setting up an outdoor link, you usually account
for this by using a "fade margin" -- making sure the received power
under good conditions is strong enough that you would still have
a signal after some fading due to weather. I have seen 6 dBi
listed as a typical fade margin, but I think that was for California:
you would expect to need less in the dessert, and more in a foggy area.


A few years ago, when we had a link a few hundred feet diagonally
across the road, the *only* time I ever saw the link go down due
to weather was during a bad blizzard (strong winds, fresh snow, lots
of blowing snow): I was barely able to see to the close edge of the
street from my window on that side: we essentially lost line-of-site
for that time. But the link did not drop during any of the rainstorms
or other snow storms or blizzards we had. I wouldn't want to promise
that an outdoor link would stay up during a tornado or hurricane!
