I will check, but I think the 5 degree spacer only comes with the 5GHz LGH dishes, not the 60GHz devices.
I can't find anything on a new R2 version. Do you have any more information? We run 5GHZ backup paths on every LHG60, but an integrated backup would be so much easier.I've heard that Mikrotik has released the new LHG 60 Ghz R2 review
for range up to 6000m and embedded wifi 5GHZ
