I have been looking for some time now to find the best sector antenna out there for 5GHz & 2x2 MIMO.
I plan on using ONE RB800 and ONE R52Hn & NV2. (no close by sector antennas=low interference)

The best i can find is this: 90° Ubiquity AirMax 5GHz Carrier Class Sector 2x2 MIMO Antennas 20dBi Hi-Gain Airmax Sector 5G-90-20

My goal is to get as much throuput i can and i plan on connecting max 40 customer antennas to this sector using sextant stations.
If i could find 60° antennas that are as good as the one mentioned i would go for two of those instead (20 customers on each).

Anyone with a better suggestion?

Airmax are good antennas but Sector 5G-90-20 has very small vertical radiation angle they are not the best for high tower (mountains).

Sector 5G-90-16 or 17 works fine in all enviroments.

My esperience: nV2 needs almoust 40/60 mhz channel spacing to avoid interference, rock metalic box with one wireless card and good separation between antennas. More wireless card running NV2 in the same box kills peformance.

Thanks for your answer server8!

I have seen that the antenna only has 4° vertical beamwidth and i have checked the distrance and angles to my clients and have concluded that 4° are more than sufficient to cover them all.
Min / max distance to clients are 2km/5km.
This sector antenna will be pritty alone on the barn so any interference from other sectors or sources will be minimal.

I am looking for the BEST antenna and if my suggestion can give me a little more speed i would prefer that one.

Any other suggestions out there?

What about the SRA_SE50016dual H&V from ITELITE? It will fit RB600 and therefor also my RB800 right?

Anyone tried that one?

rb433 with r52hn should be good to handle 40 clients and 40mbps bandwidth if that is all you need.
wy do u want a rb800?

Why rb800?
Well i want to get the best speed and the RB800 is the fasters RB i know of.
And - it is smart to standardize on one RB. I use RB800 for my PtP links also.

I think i have found the best Sector antenna with MIMO support:
60° and a gain of 21 DBi!!

Anyone that has any experiance with this antennas?

I will then need a box to house my RB800, but there are many box alternatives like:
