Hi, i tried ptp with MikroTik Wireless Wire Cube Pro at 1,8km and its not working. Can anyone tell me how is real distance that work on 60Ghz ?
See http://forum.mikrotik.com/t/cube-60pro-ac-max-distance-on-60ghz/164356/1 for achievable range.
60 Ghz is just the frequency, the Cube Pros are devices excellent within 600 m, or so, work up to maybe 1 km, not much more.
The LHG 60 and the nray can go up to 1.5 km "full speed", possibly a bit more, so you should try one of them over 1.8 km, the LHG is also sold as "wireless wire":

But it depends on your requirements, you might need a 5 GHz backup link, with rain the 60 GHz is likely to be flaky.
At that distance, with the sun and the device configured correctly, I think you should have gotten the link,
but at that distance, it takes very little to NOT center the antennas...
My advice is: Do research before purchasing,
especially regarding water infiltration issues. [ CubeSA 60Pro WATER DANGER ]
From my own tests, to remain stable, do not exceed 500m at most,
but with only a little rain, and at those distances (1,8Km) work only the reserve...
At 1,8Km you need more (I say MORE) powerful device to use 60GHz...
