Which antenna & RB for basestation?

Hardware MikroTik hardware general
1

I am setting up a 90° sector or 2 60° for about 50 customers.
I want a good speed as possible using Mikrotik RB & a sector antenna of some sort.
I will use Nv2

I am thinking of :
Ubiquity AirMax 5GHz Carrier Class Sector 2x2 MIMO Antennas 20dBi Hi-Gain Airmax Sector 5G-90-20
and this box:: http://www.balticnetworks.com/maxxwave-ubtiktm-hp-for-ubiquiti-antenna-systems.html

Any problems ? Will Nv2 work with Ubiquity AirMax antenna?

Can i get much speed with LOS 2-6km?
I plan to use RBSTX: http://routerboard.com/RBSXT as clients

Goal is 20 Mb both directions to customers (max 2-4 active at the same time)
100Mb behind the base

50 users on a single AP is not a good idea, so better split it into 2 if you can. RBSXT is good if distance is max 2km, and you can make your 20mbit/20mbit. For longer distances you must use dish 2x2 MIMO antennas and RB711 dual chain model for example. This is from my experience. If I helped you a little dont forget to give me a karma :slight_smile:))
