Recomendation for 3 Hotspots

[Costa]

Hello everyone, I am new to the ubiquiti products and we are setting up 3 hot spots, each approximately 1200 - 1800 yards away from a central backhaul location. My initial thought was to use 4 of the NS 5 (1 AP and 3 SM) for the backbone and 3 Bullet 2 HPs with a 9 db omni antenna on each Bullet. So I found out the Bullet 2HP will not be available until July so should I use the Bullet 2 or is it better to use an NS2 and connect an OMNI antenna? any thoughts or recommendations?

Use the Powerstation 2, that way you can use up to a 17 dBi omni.

Bullet 2 can only use a 6 dBi omni and Nano a 14 dBi omni.

Thanks, I just looked at the Power Station documentation and want to make sure that I understand correctly, should I use the PS5 connected to a PS2-ext at each hot spot? also should I get two 17 db antennas for each PS2-ext? Also on the Ubiquiti site it mentions powerstation5 but there are no mention to the 5 Ghz on the data sheets.
