Hi Martin,
Depends where you are located and your aerial set-up, to receive Freeview at present in your area, you need to have a suitable aerial for your nearest Freeview site which is Limavady. Most places on the cityside are okay but for the Waterside you have best reception the nearer you are to the River Foyle, you may also benefit from a mast-head amplifier prior to the power being increased in October.
Peter.

martin: It is likely that in October, it will work OK for you. So anything you do (sand spend) now (if there is anything to improve matters), will be likely to be purely to affect reception between now and October.
If your new TV has some sort of in-built booster then you could try that.

martin: BBC One, BBC Two, BBC News etc are on UHF channel 67 from Limavady, so try manually tuning to that channel if the set allows.

martin: I would also like to suggest, if only to test, connecting the TV directly to the aerial, i.e. so it doesn't go via other box(es) such as a recorder and Sky box.
