This is of course not LHG 60G limited, I'm generally interested in any 60GHz experience. Sure I know crappy plastic LHG is something different to professional grade all-metal antennas/devices etc. but Im interested in any experience
Actually it is specifically a problem with the MikroTik 60ghz. The signal isn't so bad it would actually not work, the signal is definitely getting through. However I presume the beamforming or other mikrotik implementation causes periodic dropouts and it just so happens to be significantly worse at the lower frequency (auto picking the 'first' free channel means it also picks the worst one)
Plastic has nothing to do with it, infact its one of my favourite dishes for installation. You can partially see through the dish which makes alignment by eye much, much, much better. You don't even need the included little plastic scope thing, just use it like iron-sights and align holes in the dish with the front arms and center of the radio, gets you within a bees dick if the other side is visible. Still worth using a solidmount however, mostly because the crappy stock mount WILL move when you tighten it down to some degree
co-location is fantastic, I can have them on the same mast only separated by ~50cm or so and see no drop in performance even on the same channel
They do work well when used exclusively as a point-to-point and you get it dead nuts aligned (in which case you can leave beamforming turned off entirely if it causes problems) and follow a certain procedure. The problem is when you just slap them in, then you get all kinds of black magic, they work, they don't work, there's no explanation for why, and you are given incorrect readings (like the distance to center is woefully wrong, its just garbage, mikrotik please just disable it entirely it doesn't do the 1 job its supposed to)
