Have a new Samsung Freeview HD tv and can see the HD channels after retuning but cannot view them due to 'weak signal'. Postcode is NR29 4NQ. Is it possible aerial is not pointing at Tacolneston but some other transamitter?

Trevor Wadsworth: Looking at the predictor it's doubtful.
Tacolnestion is at 238degrees (between South West and West South West) with your aerial mounted horizontally. See here for a picture of a horizontally mounted aerial:
Aerials, TV Aerial and Digital Aerial
On the signal strength screen it should say that it is tuned to UHF channel 62 (when you have it on one of the HD services).
I had a quick look at your area on Google Streetview and all the aerials I could see are on Tacolneston. I did see a few bungalows, which by their very nature does mean that aerials are lower to the ground. Also look to see if there are any trees in the line of your aerial. They could affect some frequencies (multiplexes) and not others.

I'm in bowthorpe, Norwich and we cant get any channels whatsoever and had the same problems with signal that Ann had before the changeover. It is so annoying considering I've paid for a licence and cant watch tv :(.

Hollie: If you have a signal booster, remove it.
What sort of reception did you have before switchover?
Can you not get any TVs in your house to work?

Hi. Since the switchover my Thompson PVR cannot recieve any channels to a watchable degree (they stutter/glitch constantly). Before the switchover I used a booster with the device and it always recieved all channels without a problem. Since the switchover I have tried it both with and without the booster (also altering the boost rate on the booster itself) but it makes no difference.
I live at NR9 4JL, have and external ariel on my roof and other TV devices which all work ok (including a TV on a portable ariel) - none of these require boosters.
I understand that the Thompson PVR may be old/not a top make, but it did recieve all channels okay before switchover. I've tried retuning it several times in the last week. On some occasions it only pickups a few channels, sometimes it pick up all of them, but they are never watchable. Is there anything which is going to change, or that I can do? Many thanks.

Chris: If the set-top aerial works fine on the Thompson PVR, then I suggest that the problem might be too much signal.

Oh sorry, I meant the portable ariel is working okay on a different TV. However, I did try the portable ariel on the Thompson PVR but I couldn't recieve any chennels like that.

Thanks Dave, I'll check the things you suggest when I get home at the weekend. Using Google Streetview though (I hadn't thought of that!) the aerial seems to be pointing in the right direction and is high enough but is of standard rather than digital high gain type. Would upgrading the aerial help much do you think?

For years we have been told that all we need to do is buy a Freeview box anc connect to out existing aerial.. I bought a Freeview + box..Since Tuesday 6th December it hasnt worked because Norwich council cut the communal aerial.. telling me that that it didnt work because it wasnt a digital aerial and woudlnt receive a digital signal!!!! and that I will have to get cable or buy and aerial for the house...

Chris Wildey: This sounds like the council is no longer prepared to pay for the communal aerial to be maintained, the contract to provide and maintain the aerial has possibly expired. Whilst there is no such thing as a digital aerial there are certain adjustments that may be required to accommodate changes in frequencies and transmitter power following DSO. Some councils made a decision to replace existing communal aerials with an all singing and dancing version which also provides DAB radio and satellite services for Sky and sometimes foreign channels, this came however at a price which many tenants complained about, especially if they had no TV, only watched terrestrial channels or were cable subscribers! That is why other councils decided to let tenants choose (and pay for) their own method of viewing TV.
