jpreece: Extremely doubtful.
There's no such thing as a "digital aerial" as against "analogue aerial".
What you would be trying to do is receive from Wenvoe, as it carries all the channels. However, even though it's only 12 miles away, you're a long way off seeing it, as this terrain plot shows:
Terrain between ( m a.g.l.) and (antenna m a.g.l.) - Optimising UK DTT Freeview and Radio aerial location
All in all, think you're better considering Freesat.

Chris: Hi. My name is Anthony. I have a similar problem in that a few weeks ago we lost a lot of channels to our freeview box. Our nearest transmitter is Wenvoe and we live in Llanedeyrn, Cardiff. We can get BBC 1,2 3 & 4 and some others like Yesterday, Drama, Pick, ITV3, etc.
No ITV1 Channel 4 or 5. and loads of others are gone.
It sounds like the same problem you had, although the lost channels are different.
Did you find out what the problem was?

I live in The Morriston area of Swansea and get my signal from the Kilvey Hill transmitter. Will I ever be able to receive BBC4 in HD. I find it very frustrating that I can only get a standard signal on one of my favourite channels. I would love to see the Christmas lectures in HD. I cannot receive a signal from any other signal as far as I know.

John Preece: Unfortunately Kilvey Hill is not listed as one of the stations in line for providing an extended HD service, a few test p/codes from around the Morriston area entered into the terrain indicator revealing large multiple line of sight obstructions between the Wenvoe transmitter and the location covered by all of the test codes, this reflected by that seen on the reception predictor using the aforementioned test codes.
The only way full programme channel coverage can be obtained is via Freesat.

Why can't I get ITV3 (Channel 10) on my Freeview tv. I live in the CF46 area (Nelson)

Thomas: There are 11 relay (PSB only) transmitters dotted around the CF46 postal code area and one main full service transmitter, namely Wenvoe.
As relays do not transmit commercial programmes such as ITV3 whereas the main station of Wenvoe does on COM4 Mux C42, its really a case of whether or not you reside in an area with a chance of picking up Wenvoe, a post code being required for checking.
