brian: I think that getting an attenuator would be the best bet.
You are only 5.6 miles from the transmitter and the terrain plot suggests that it might be visible from your rooftop. So yes, too much signal is a possibility.

..Sorry, got cut off mid flow. I was going to say if that is the case then I can not be alone. I am at 2 metres AOD and just about everyone has a roof top aerial. If it's happening to me it must be happening to plenty of other folks. My set up (with a splice) is far from efficient !

brian: eBay has variable ones for £3.15 (other suppliers and models are available):
TV Aerial Attenuator Variable 0-20Db Freeview Digital | eBay
Granted, you may be pushing it to get it before Christmas! Failing that, maybe you can find a seller that is local to you and which will allow collection.
Or by connecting the centre conductor without the screen might reduce the level enough (until you get a proper attenuator).

Thanks Dave, I have bought the attenuator + will try to reduce the signal tonight till it arrives (should be a lot easier than trying to increase it) !
Thanks for your help. I will send you an update (as I am sure you are hanging on the news) !

brian: I would reduce it more than just that needed to get a stable picture (assuming that too much signal is the issue).
Being "just below" a level that is too high could be an issue if the level increases slightly (due to the weather etc). Leave room for this.
The picture isn't better when the level is higher, thus the objective isn't to get as near full signal strength as possible.
...Yes I await your news. Just hope that your dad hasn't paid an installer to add an attenuator.

Hello Dave,
Just so you konw the attenuator arrived in the post the next day.
I was about to fit it when I noticed the picture was fine on the D26 MUX. Four days later and it is still fine. The problem was definately too much signal as I can see the signal strength is slightly down on this MUX compared to the others.
I will keep my £3 investment in a safe place lest the problem occurs again !
Many thanks for your support and advice and I have noted your comments about signal strength reduction above.
