Recently we lost all stations on channels 48 (Film 4 etc) 51 (ITV3 etc) and 52 (Pick tv etc). All BBC channels, ITV1, C4, C5 etc are excellent (Channels 27 and 24). I installed a new aerial, still same problem. Same on both TVs, manual and auto retuning does not help. Any ideas?

I went to my local chip shop the other day and noticed an aerial looking at Sandy Heath.
Nothing too unusual in that except that my chip shop (Mr Fast fry) is in Greenwich, South London.
I looked at the postcode checker and there is a 90% plus signal there on all the main MUXs .
Same if I put in sample postcodes in SE18 or SE2 further along the river Thames.
There have always been a few Anglia TV aerials along this stretch of river but always looking at Sudbury not Sandy.
Does anyone know if Sandy has had a major change in its radiation pattern? The digital power seems in proportion (at less than 1/5 of analogue).
I did a plot using this site Terrain - shows radio profile between two UK sites to optimise you DTT, Freeview, DAB or analogue TV reception and the path appears well and truly blocked several times miles away.
We are about 5 metres AOD and are 73kms away from Sandy!
My signal from Crystal Palace is fine by the way (SE10 0AE), I am just curious how such a strong signal penetrates south of the Thames.
(SE100AE)

brian: Have you checked to see if the chip shop is actually getting the Anglia regional news? Because I can see two aerials by looking at google street view - one north, one south.

Michael: I'd be more concerned that if I ordered haddock I got haddock and if I ordered cod I got cod.

Michael : Maybe Mr Fast fry himself is not watching news of school closures in Peterborough but one of his clan is as you can see from your poke around his roof top with google street view the aerial is one of them new fangled 3 pronged 'digital' ones you didn't get in the good old days, Dave : His skate is very good but you need to wait 10 minutes for it..

nick: Maybe it would help if you told us what channels you're missing instead of typing out all of the muxes.
Is everyone else in the flats missing the same channels? If so it could be an aerial problem, as you do need a wideband aerial to get all of the commercial channels from Sandy Heath. Also, HD channels won't show up unless you have a DVB-T2 tuner inside a box or TV.

We have previously received all channels but within the last week we have a greatly reduced channel selection. We have emptied and rescanned with no change.

in the last couple of weeks our ITV channels
from Sandy have been very poor and breaking up. we did a signal check on each channel and it comes up with "poor ". all BBC and other stations are strong and come up with a full green signal strength, the ITV,s are all yellow with step backs to red ( very bad ) occasionally.
I have reset all freeview settings more than once but problem is still there please comment ? thank you
