This would get really bad rain fade at 80GHz or even on a humid day the speed would back off a lot. You need to run a lower frequency backup link in parallel.

That's the nature of 80 GHz, design the links for your climate and don't try to go more than 2-3km. You can achieve five nines. And yes, run a 5.x GHz backup path in parallel.

As long as nobody pilots a drone in the path.

It'd have to be a big ass drone, I have links that stayed up when a Canada goose was sitting 2 ft directly in front of the 60cm antenna on one end.
