Lesley: In your general area the Sandy Heath transmitter is the main one. You may find that your aerial is not sufficiently sensitive to receive the COM channels because Sandy Heath is one of those transmitters where the COM channels aren't within the same frequency range as the former analogue (and therefore within the range of aerials). Sandy Heath is roughly east and your aerial will be horizontal (elements flat).
There is a relay transmitter at Dallington Park which is essentially a low power "filler-in" primarily intended for those who can't receive from Sandy Heath. If your aerial points towards this station then it will be vertical (elements up/down) and it only carries PSB channels.
In some cases it may be possible to change from using the PSB-only transmitter to using the full-service one, but this would be likely to require replacement of the aerial.
Refer to this page for a full list of Freeview services:
DTG :: DTT Services by Multiplex
Each table is a single signal known as a multiplex. There are six in total: three PSB (including one HD) and three COM. There is a small proportion of the population who can only receive the PSBs, so COMs aren't guaranteed even if you can receive PSBs.

Lesley: I would like to emphasise that you should try it whilst bearing in mind that you may only receive PSB channels.
If reception of the full Freeview service isn't possible or might require a new aerial then another alternative is to use your satellite dish to receive free-to-air services via the Freesat service. These two systems are identical as far as the dish is concerned.
A comparison of Freeview vs Freesat channels is here:

For example, Dave and Yesterday are available from full-service Freeview transmitters (i.e. COM channels) but not Freesat.
All services carried on the PSBs are available on Freesat.

Lesley: You will need a Freeview receiver, whether built in to your TV or a set-top box. The Sky box will not function as a Freeview box.

simon: Possibly.
The Digital UK predictor suggests that you might (predictors cannot ever be absolutely accurate).
Also, have you looked to see what are neighbours doing?

william walsh: The channels broadcast by the Castleberg transmitter are available to the rest of Northern Ireland.
The channels that aren't available from the Castleberg transmitter are the Commercial ones and these aren't broadcast from any small transmitters because the operators don't consider it worth their while. They aren't ever likely to increase their coverage and particularly so for a transmitting station which serves only 1,200 homes.

Tez: Looking at your close proximity it could be caused by the strength of the signal overloading your receiver. See:

Colin Anderson: Some thoughts:
- Which transmitter are you using? Could it be that BBC channels are found last during the scan and when it's run out of memory? The solution would be to prevent it from finding signals from other transmitters first.
- There is an RF modulator in-built. Is this co-channel or nearby to BBC channels from your transmitter?
- Have you tried a manual scan for the BBC multiplex?

woodface: The stronger the TV signal the less prone to interference it will be from the same level 4G 800MHz signal. This is because the TV signal will be "louder".
