Hello. Just after a little advice if possible.
Postcode is CF484RT.
I am right under the Ynysowen transmitter, but if i understand some posts here i may be better off trying to retune to the Wenvoe transmitter.
Is that a matter of re-positioning the aerial i have which is currently out the back pointing upwards to the transmitter? I'm guessing the aerial is quite old also so would it be worth upgrading it?
Thanks

Barry: It is quite possible that the aerial you have now is a Group C/D one, which means that it is specifically designed for a certain range of frequencies (C/D).
Wenvoe uses Group B channels (frequencies) and so you will probably have to have a different aerial for this reason alone. For Wenvoe your aerial will need to be horizontally polarised, rather than vertically so for Ynysownen.
You don't have direct line of sight to Wenvoe, so I would be surprised if you might need a larger aerial. Have a look around at your neighbours and see what they have done (if they use Wenvoe).

Barry: Sorry, my reply should say that "You don't have direct line of sight to Wenvoe, so I would *not* be surprised if you will need a larger aerial."
A look on Google Streetview shows that houses adjacent to Top Gear Garage are on Wenvoe.

Cheers for the advice Dave.
We have an old Sky box from an expired subscription so can pick up the residual channels from that, but at some point that's going to stop working and i want to be as best prepared for that day as possible.
I may just get someone in to see if they can check if we could get the signal required from Wenvoe.

David Rolles: It's a good idea to confirm that the TV is tuned to the signals from Wenvoe and not Ynysowen or Methyr transmitters.
Ynysowen or Methyr only broadcast Public Service channels, so Commercial ones must be coming from Wenvoe.
Look at the UHF channel it is tuned to on one service from each multiplex. This information is usually given on the signal strength screen.
BBC One is C41 from Wenvoe, C59 from Ynysowen and C25 from Merthyr. ITV1 is C44 from Wenvoe, C55 from Ynysowen and C22 from Merthyr. BBC One HD is C47 from Wenvoe, C62 from Ynysowen and C28 from Merthyr.
Because of the spacing out of the frequencies used by Wenvoe and the other transmitters, it's possible to have the aerial unplugged for parts of the scan to ensure only Wenvoe is picked up.
Have it unplugged up to 30% and then unplug again at 65%.

Hi
I live in Pentrebach, Merthyr Tydfil CF48 4BQ. Have a high gain freeview aerial mounted in loft tuned to Ynysowen transmitter. On weekend, lost all BBC channels, all other channels were fine. Tried re tuning but no improvement. Channels came back last night (20/3/2012). Hass there been any work on transmitter that may have caused the problem does anyone know?
