On this link I found this https://help.mikrotik.com/docs/display/ROS/W60G
Is it possible to use 70.20 GHz on LHG60 with the US region?
The better frequencies are also generally reserved for licensed bands - not 'class license' or 'open' bands - as such the restrictions are based on local laws not on capabilities. Mikrotik could make a radio and antenna to run at any specific frequency they realistically wanted - but could risk being sued or banned from a region.I hope that Mikrotik will unlock more frequencies for LHG60, considering that the frequencies that are at 70 GHz have considerably less attenuation of radio waves in dB/km. And it is possible to achieve a more stable link at greater distances.
