ThanksPixelation is a signal issue.
Either your aerial is out of alignment or cable damaged, failing that you have chosen the wrong area/region.
Did your tv have signal issues like the above before you got the H7?
What’s pixelation ?
Don’t think my aerial is out of alignment but on the check @bmitie said the area is coming up pass spur hill nearly going through it to Mull but that option isn’t in the area /region
