DemThonp: Do you have a Freeview HD television, or an "HD Ready" TV with Freeview?
You need a DVB-T2 ("Freeview HD") receiver to get the HD channels. If you set isn't marked "Freeview HD" or "DVB-T2" you will need to get a set-top box and connect it via one of the HDMI inputs to your TV.

DemThonp: General advice for siting your aerial is to see which direction the signal is coming from. Then consider what things are in the way in that direction, eg a building, and think whether you can move the aerial to somewhere away from the obstruction.
The point is that these things can cause shadows as far as the signal goes.

DemThonp : Indications are that your location is line-of-sight with the Winter Hill transmitter @ 27miles / 126°.
However, you should carry out a signal check on the HD channel you are viewing to make sure that you haven't picked up Lancaster's HD service rather than Winter Hill, Lancaster's HD being on Mux C21 whereas Winter Hill's HD is on Mux C57, and with its new COM7 HD service being on C31.

DemThonp: No!. The channel numbers you have given correspond to that being used by two different stations, namely Lancaster and Moel-Y-Parc, neither of indicated as providing the best signal in your area. Nearly all of the aerials seen in the Falkirk Avenue area are pointing towards Winter Hill, therefore you should delete everything stored in your TV tuners memory by removing the aerial followed by carrying out an auto-tune, reconnecting the aerial on completion to ensure that "no signal" is indicated if you try to select a channel Should this be the case, then the next stage is to go into your TV's tuning menu / "manual" tune / and enter the following channel numbers "one at a time" followed by scanning each of them in turn and storing the results. Winter Hills channels being / C50 (BBC) - C59 (ITV) - C54 (HD) - C58 (ITV3 etc) - C49 (Pick TV etc) - C55 (4Music etc) - C31 (this being the new COM7 HD service)
