Chris.SE,
Sorry for the late reply only just got the email to say a comment had been added.

Postcode is LL68 9NE but the Penysarn side of the hill. I assume that hill must be the problem! I have not changed anything and not been here long enough to know if more channels were ever available.

Hello, happy new year. The Freeview Detailed Coverage Checker shows that most properties in your postcode should get all the multiplexes from Llanddona, if you are tucked in close to that hill (even though it's not that big) it could be a problem.
Having had a look around on street view, most aerials I can see are pointing at Llanddonna but I also noticed one or two pointing at a low power relay at Amlwch - it's only 3-4 kilometres away, but these are "Light" transmitters and only have the PSB multiplexes, see Channel listings | Freeview (note there's no COMs 7&8 at Llanddonna).
There looked like quite a few properties may have loft aerials as no external ones were visible (not recommended unless you do have a very good signal).

For reception from Llanddonna, the aerial must have its rods horizontal and be pointing ~SE (127 degrees). The relay at at Amlwch is at bearing 304 degrees ~NW with the rods vertical (almost directly the opposite direction to Llanddonna, but it is very low power. I did spot an odd aerial pointing towards Arfon, some way to the south but that again is only a "Light" transmitter. I saw one I could swear is pointing to either Moel-y-parc or Winter Hill, couldn't be sure which, but reception from either is likely to be variable to poor for a lot of the multiplexes.

So you need to check which way your aerial is pointing ~SE with rods horizontal, or NW with rods vertical. If it is pointing SE, any idea how old it is? Try and look at the state of the coax downlead. Does it still look in good condition, or does the outside seem hard and brittle?

Have a chat with your immediate neighbours, see which way their aerials point, and if you need or decide to go for a new one, find out from locals who is a good knowledgeable local installer - there are a few who just shove an aerial up and hope for the best!

Chris,
I am tucked close to the hill and think that is the problem.

Thanks for your help

Hello Fred, you haven't said where your aerial is, whether the rods are horizontal or vertical and which way it's pointing!
Is it accessible? If you can see the end of it, can you see if it has a colour bung in the end?
The bung might be Green, Yellow, Black, Brown, or if pointing at Amlwch it could be Red or Grey.
