Hi Tom,

Your best best bet is Freesat, in the install menu type in a welsh postcode & you will receive bbc1 wales / bbc2 wales / itv1 wales / s4c in their primary positions on the EPG.
A basic sd freesat install can cost as little as £110 which could well be cheaper than a aerial installation in this case.

Tom,Mark is correct.But if you were looking at an Aerial only install,just to feed to your main outlet.May i say wait until after Sept 28th 2011.Combine two Aerials.Wideband Aerial directed at Wrekin and High Gain Group CD Aerial directed at Long Mountain,on the same mast,into the appropriate Diplexor,connected to your downlead.Digital signals in your area are strong enough to combine without amplification when both transmitters settle on final powers and frequecies/channel numbers,after the above date.I dare say that will cost more than £110.

Just to add to the above,your welsh services are likely to be assigned to the 800's,on your freeview TV/set top box.

Thanks for the responses, I've realized that the Breidden is between our location in Oswestry and Long Mountain. In fact Rodneys Pillar is directly South of us, so we are unlikely to get a decent signal from Long Mountain.I think that Freesat is the way to go for the Welsh programmes.
Many thanks
Tom Williams.

This transmitter has had digital Freeview since 2009.
Some won't get it until 2013.
I'm sure there are a few people who think their transmitter is worse.
