as Clarkson says 'Sit-rep!' - so months/ years or repeatedly trying to et things correctly aligned to be able to get channel4-7 and Yesterday, Dave, Drama etc - the only channels that never worked for me, all of a sudden this weekend I found them all working to a greater or lesser degree - signal quality was next to 0% but they worked.
SO what's changed ? has the dish moved ever so slightly in wind etc ? has the signal strength got stronger ? or is it just the clear winter skies ? - I assume the latter.
Am very happy they're working and ant to tweak it juts a little more to see if I can improve but each time I do that I make things much worse so lesson learnt will leave it alone.
