Just to add the aerial rods (or squashed Xs) should be horizontal polarisation.

Can't find any reported faults at present for the Mynydd Machen transmitter.
Have you checked your aerial still looks intact and is pointing correctly and that the coax downlead isn't flapping about in the wind?
Also check all the connections behind your TV.
Have your nearby neighbours got no signal?
If neighbours don't have signal either, try phoning the BBC.

There is also this -

Do NOT Retune if you have No Signal - you cannot tune to signals that aren't there (whatever the cause), the usual result is to clear the correct tuning you had.
If you have already retuned and still have no signal, try a manual tune on the following UHF channels for the Mynydd Machen transmitter. UHF C23, C26, C29.

Hi. Sandy Heath is 18km from you, compass bearing 81 degrees (9 deg short of due E).
You should get excellent reception.
Ideally you need a Group K aerial, though a wideband would do, but might leave you vulnerable to interference from any new/upgraded mobile phone mast using the 700MHz band. There's at least 9 masts within 1.5km of your postcode.
If you suffer interference, you may need a Free Filter from Restore TV, you should have had a postcard from them.
Sandy Heath Grid Reference is TL 20472 49446
