Which companies have run the Channel 3 services in the Divis transmitter area
Hi will the divis transmitter have a strength upgrade before the digital switchover as my picture quality is clicky and jumpy when windy or heavy rain.And as we all now thats 6 months of the year minimum here in n ireland.My equipment is new and good 75 per cent of channels work well at present.

Noel: I cant really see your situation improving until October 24th when Divis (@ 32 miles) switches over to full power operation, as the multiplex that ITV4 uses is only transmitting on 1.6 Kw whereas it will 50kw as from the date mentioned, the reception in your area presently predicted as being non existent on some channels and poor on others, the ArqB mux that ITV4 uses being the only one of the five with a prediction in the green, this being good. (in theory anyway!).

Hi we live at foot of divis and blackmountain bt127hf we had a digital aerial fitted but can only get a few channels ie yesterday film four the guy said that we will have to wait ontill black mountain starts relaying the signal is this right

According to Digital UK's postcode chaecker you should be getting excellent reception from Divis at the moment, and after DSO. You should also be able to receive the NI mux from Black Mountain on October 24th.
Check to see which transmitter your aerial is currently receiving. If it's vertically polarised (i.e. the elements are up and down) then it's Black Mountain. If it's horizontally polarised then it's Divis.
Another way to check is to see if you're getting a good picture from Channel 5 analogue.
Personally, I'd seek the advice of a reputable aerial installer to see exactly what you need.

MARGARET MARTIN: The answer to the question would depend on which transmitter the new aerial is directed at.
I should say that there is no such thing as a "digital aerial". Aerials are designed to pick-up particular frequencies. In some cases a different aerial is required for digital reception because the frequencies used are different to the former analogue.
As Peter Henderson says, Digital UK does predict "good" reception on all channels from Divis now. However, such predictors should always be taken with a pinch of salt as there are other factors not taken into account.
I had a look down your road on Streetview (photos taken August 2008) and most houses have two vertical aerials (or did then). They would appear to be pointing at Black Mountain and Clermont Carn (for RT, TV3 and TG4). I spotted only one horizontal aerial on Divis.
This leads me to think that reception from Divis is difficult because there is no line of sight to the transmitter on the top of the hill. Furthermore, I should think that if you can get any digital from Divis now (bearing in mind that it's on much lower power than after switchover), then you're lucky!
It would appear that the only two transmitters north of the border that you can receive (if at all) are Divis and Black Mountain:
- If your new aerial is on Black Mountain then it will be vertical and pointing a bit anti-clockwise of west. This does not carry any digital (Freeview) now and after switchover will only carry Public Service channels (these being all BBC TV (standard definition and high definition), BBC radio stations, UTV, UTV+1, ITV2, Channel 4, Channel 4+1, Channel 4HD, E4, More4 and Channel 5 (I assume UTV HD if there is such a channel).
There should be no need to replace aerials on Black Mountain as the channels (frequencies) used after switchover are the same as those used for the current analogue. Only where viewers change transmitter (probably to Divis) to get the full service will a different aerial probably be required.
- If your new aerial is on Divis then it will be horizontal and pointing roughly north-west. Divis broadcast all Freeview channels after switchover, unlike Black Mountain which will be "Lite".
The fact that you can receive one of the multiplexes suggests that your new aerial is probably pointing at Divis. If not, then you must be receiving it with the aerial not pointing at the transmitter and with the aerial vertical when the signal is horizontal.
If your aerial is on Divis, then all you can do is try manually tuning missing channels (if your receiver allows). The rigger has installed the aerial based on the signals that can be received now. You will have to hope that the boost in power in October will be sufficient. I'm not sure whether you have recourse with him if it's not because he can't know for certain whether the aerial will work come October. For this reason it would perhaps have been pertinent to have the aerial changed after switchover.
By the way, the changeover will happen in two stages. On 10th October BBC standard definition services will go on full post-switchover power. These will take the place of BBC Two analogue. BBC One, UTV and Channel 4 will continue to be available on analogue.
Two weeks later on 24th October the other analogue channels will go and the other digital ones will go on full power.
