We have line of site to the Llanrhaeadr YM transmitter, which is about 2 miles distant. The BBC Wales channels disappeared on the 7 Sept when the Fenton switchover started. The aerial is pointed at LYM not Fenton, but I assume picks up a strong signal from the side as we now get English channels on C24 and C27, as well as Welsh channels on C49, but no longer any C45.
I'm going into Llanrhaeadr today (my once-a-year visit) so will ask if anyone else has had same problem.

Yes other people in Llanrhaeadr have also lost BBC Wales since Central went digital.
Should I contact mast owners ITV Daybreak?

Paddy: At that postcode it looks like the problem is that Sutton Coldfield now (since 21 September) uses C42 and C45, and those transmissions are powerful enough to knock out LYM.
You're not really in the planned service area for this transmitter, the radiation pattern shows a -7 dB (80%) reduction in your direction.
The alternative Welsh relay listed by Brian's predictor, Llanfyllin, uses the same channels as Fenton's commercial multiplexes, so again, Digital UK offer no prediction for either Llanfyllin or for Fenton's commercial multiplexes.
The mast owners are Arqiva, but you can only blame the planners and the regulator for this. The easiest option may be Freesat. It's certainly possible to build antenna arrays that are more directional than a single antenna, and to get more directional/higher-gain aerials, but honestly, a satellite installation is cheaper.
If there is a large population that's affected, you could talk to Ofcom about a self-help relay: Ofcom | Self-help TV Relays and Digital Switchover

Thanks for that extremely clear explanation Mike: As you say, Freesat seems the best solution for the present.
I will put a request in our community newspaper asking for people with a similar BBC Wales reception problem to get in touch, and if enough interest, pursue the self-help relay route for a long term solution.
Thanks again for your help
