Don't really see where you are going with this. Everyone's performance here has changed by the same amount, so nothing to do with the install.What is the elevation on the dish/LNB for this satellite??

It could be a signal bounce that is caused be certain weather conditions, water or ground temperatures and atmospheric temperature variations from season to season.
This bounced signal would be 180 degrees out of phase from the main signal, when the bounced signal gets close to the right amplitude it will cause a drop in the main signal, this is called phase cancellation, and is a common in microwave signals, the bounce is determined by the elevation of the dish/LNB and what ever is causing the signal to bounce.
RF signals can bounce off things, just like Sun light bouncing off the heat of the road, thus causing a mirage in the road that looks like water, and it disappears when you get closer to it.
My dish was aligned in february on 10818V as 2E was weaker than 2F for me, now the channels on 2F seem about the same as in february but all the 2E channels are gone or much weaker. Has 2E moved that much between february and now or has the UK spot beam been tweeked as no other channels seem affected on 2A or E28A?

Overall signal is now down by 1dB SNR on all transponders compared 4 months ago. If it drops much more everyone in Torrevieja with a 1.4m offset dish is going to lose BBC/ITV.
