Not sure if I'm too late. But I've used Ubiquiti radios before, specifically the 60ghz ones. The 60 ghz radios have been extremely reliable, no matter the weather (setup in Chicago so its seen rain/snow/sleet whatever). Essentially no downtime. I would probably recommend their 5ghz products if you've never used these radios before however. Reason is because the 60ghz has a very narrow beamwidth and you need to be very precise when pointing these at each other to make the link. There's not a lot of freedom. 5ghz should be much easier to get up and running and should be just as reliable, if not more.
Power is via POE injector, just make sure you get the right one because they have different ones with different voltages.
Software/setup I wouldn't say is 100% beginner friendly. If you have basic knowledge of TCIP & networks you should be fine (how to setup network name and IP addresses mainly). But it's definitely not plug and play.
5Ghz link should get you a reliable 300M, 60ghz link can get you anywhere from 500-900M depending on how good of a link you can setup.
Hope this helps.
