Ubiquiti airMAX NanoStation 5AC Loco

Hi,

I plan to order two airMAX NanoStation 5AC Loco devices to create a point to point bridge over a 180m distance. Unfortunately with two trees in between.

As I have seen openwrt is supported here I wonder if there might be a difference in range and thruput between openwrt or airos with airmax support?

And in general what is your opinion on using these quite cheap devices for such a gridge? What thruput can I expect?
Or maybe any other device recommendations?
