speedtest is not all telling feature. If you want to see if it can go faster try to type in the speed you want (9G for example) and see the real speed on the interface and on the interface of the other mikrotik device.

I Have a bad experience with radome. When it rains that radome stays wet and signal drop a lot even few hours after rain. By my tests radom is not recomended.

Matess

1,7km at 1Gb/s full duplex is achievable. Not more than 1km in heavy rain is not possible.

we have custom made antennas on WAP and on 1km test link it has 4dBi less then LHG60 on the same link. 500m link still drops with heavy rain. 420m is rock solid.
