My experience with LOS and NLOS is don’t expect NLOS to work too well in rural or suburban areas.

The marketing hype from major companies touting NLOS conveniently fail to mention all their testing is done in urban areas with lots of nice hard surfaces for the signals to reflect off.

In rural or suburban areas you usually have lots of trees and vegetation covered hills which tend to absorb microwave band signals rather than reflect them.

NLOS will only work if there is something to reflect the signal off to get around the obstruction.

I now only install connections where I can physically see the transmitter and the fresnel zone is clear. You just store up problems by installing in marginal conditions. It’s better to have no customer at all than one who has a poor connection, they’ll just tell everyone your service is rubbish and make it harder to get customers where the signal is good. I speak from bitter experience.

The only real answer is to install more APs so that you have clear LOS.

SR2 or XR2 in a rb133 or rb532 with a high gain antenna. then run it at 5mhz bandwidth. I think this is about as good as it gets.

While a sr2 or xr5 would be fine with the options posted above … nothing tops the sr9 in terms of range and los; provided the spectrum is “clean”.

… But you should be able to run a sr9 in a “medium” noise enviroment with hori. pol. antennas with 5/10mhz bandwidth options.

I have been playing with them from the day they came out and all I can say is that the sr2 works better for me. Maybe I’m in a high noise area

I have a SR9 AP on a 260ft tower with a 9 dbi Yagi. The AP was registering a -72 Noise floor and my client links were linking but unusable.

Get the Ubiquiti Cavity filter. I put it on the AP and Voila! -95 to -97 Noise floor. The cavity filter works wonders.

All very true and well said.
