Alex Theo: I doubt you will receive from Mendip (although, as I say, I'm not a professional). See this terrain plot from you to Mendip:
Terrain between ( m a.g.l.) and (antenna m a.g.l.) - Optimising UK DTT Freeview and Radio aerial location
The high ground about 2 miles away from you is Graig Llanishen and it is about 200m above your ground level. A look at the predicted coverage map on this site suggests that up until that point reception from Mendip may be possible.
The gentleman in Bedwas lives on the north side of the valley. That is the side of the valley that faces Mendip, even if it can't quite be 'seen' at his location.

Alex Theo: I should point out that the coverage maps are a rough guide and should not be interpretted as being indications of where reception will definately or will not definately be possible.
They indicate where the signal is expected to be at a particular level and a particular height above ground.

Dave Lindsay: Thanks again for your help Dave. I may give Mendip a try anyhow but failing that I will probably look to freesat as an alternative. Not something I wanted to do but may be no other choice.

Alex Theo: My apologies. Van Terrace is horizontally polarised as the photo of it shows (the two horizontally polarised logs at the top):
mb21 - The Transmission Gallery
Digital UK Coverage Checker also says that it is horizontally polarised.
It's certainly the case that at Bedwas, Van Terrace is on a close bearing to Wenvoe.
However, this terrain plot from you to Van Terrace suggests that the ground around where the interchange is is perhaps 30m or more above where your aerial will be:
Terrain between ( m a.g.l.) and (antenna m a.g.l.) - Optimising UK DTT Freeview and Radio aerial location
Also note Van Terrace's "dickie bow" shaped radiation pattern, so the full force of the 2W isn't being beamed in your direction.

Hi. I am looking to install a new aerial at my property, but would rather connect to Wenvoe as opposed to Llanharan.
Looking at the terrain between the property and the transmitter am I likely to get a decent enough signal?

CCob: The only exact answer is to try it out.
However (I speak as someone who isn't an aerial installer) it would seem not too bad. Digital UK suggests you might be in with a shot and Streetview shows aerials pointing to Wenvoe (have you looked around at neighbours' houses?).

Dave Lindsay: I'll take a look at neighbours houses later when I get home.
I Didn't want to splash out on the correct B type antenna for Wenvoe as Llanharan uses the A frequencies. Would a simple indoor aerial work for the test?
Thanks

CCob: You can always try it and see what you get. As I say, I'm not a professional so wouldn't want to go too far as I don't have experience.

CCob: Whether a simple indoor aerial would be OK for a test or not is dependant on if it can be tried out along with a TV in an upstairs location, and if it can then to aid aerial positioning go into your TV or boxes "manual" tuning menu and enter Wenvoe's BBC on mux Ch41 but do NOT press search or scan, because if any signal is being received it should be shown on the strength / quality indicator after you entered Ch41.

jb38: Trying it up stairs shouldn't be an problem, In fact I can probably get up the attic where all the coax cable is coiled up ready for the aerial and attach it directly to one of them.
Dave Lindsay: Checked some of the neighbours houses, some appear to be pointing at Wenvoe the others at Llanharan, so it looks like I could be in with a shot.
Thanks both for your help
