At your customer, but i fell off the chair.
Customer : ‘I’m not getting the speeds you advertised’
Me : ‘Let me take a look… hmmm -85/-90 .. that’s not good’ .. can you send me a picture of how you mounted the dish?
Customer : ‘sends whatsapp with image’
Guess that’s what happens when you let customers mount the stuff themselves 
.. don’t worry : NOW he KNOWs how to mount it 
You should have launched a satellite and placed it directly in front of the SXT’s alignment.
Companies that don’t go the extra mile for their customers deserve to go out of business.
There was a special topic for this kind of posts: http://forum.mikrotik.com/t/not-to-do-weird-instalations/28333/1
It used to be pinned, but not anymore.
In the geosync satellite case, the extra 26199 miles… 
I almost said geosync - but since the SXT is pointing directly at the zenith, unless the site’s latitude is less than 1/2 of the SXT’s beam width, the satellite won’t be able to link up to it.
I suppose he could just have a helicopter hover above it with a relay radio. That sounds reasonable.
The fuel cost would be a killer though…
How about a drone, moored with electric lines? Yes! That’s it! We need a POE drone, to deploy this kind of installation! We should open a requested feature: An RB, with POE, 6 propellers, auto stabilizing and 3 miniPCI slots!
It would be a killer, I say.
Now that’s what I call IP mobility!
Haha at least they didn’t mount it in their basement.
Maybe the customer wanted to control a drone with WiFi, and his home router was not strong enough to cover several 100 meters… And since drones go straight up, so it is reasonable… hi…hi…
