Quality drops randomly

[coowill]

I have recently moved into a new build home and had Sky installed in Ballincollig, Cork. 

My Sky Q signal strength is 70 but my signal quality drops from 90 to as low as 30 sporadically. 

There are no obstructions to my dish and the cabling is all tightened, well-fitted etc. 

I have had engineers come and 'help' but Murphy's law, the signal quality is always 90 when they are here.

I am struggling to notice a pattern of quality dropping and there seems to be no valid reason whatsoever. Furthermore, the engineers don't really provide any further insight. 

The only reason I have Sky is for UHD football as I live in Ireland and no other TV services offer this. 

Any help with this would be greatly appreciated.

I don't have any fixes but keep an eye on the weather too when it drops off. Rain and even wind could impact if something is off.

Unfortunately this happens every day at this point. And at random times. 

I am beginning to think it might be because I have a Starlink set up.
