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)

hector: 60% is at the lower end of what is considered acceptable as far as the reception level of "quality" is concerned, however when you say that all channels are 60% apart from the HD channels are you meaning that nothing is being received on HD?, because should this be the case then are you sure that your TV is not just a Freeview HD ready model? as these types can only display and HD image from some externally connected source as their tuners are not capable of receiving it, HD reception requiring a TV or box to be fitted with a DVB-T2 tuner and "not" simply DVB-T as used for normal SD reception.
If you have the instruction manual for your TV have a look in the specifications section / tuner and check what's mentioned under that heading.
Should you experience any problem in finding this info, if you come back with the model number of the TV in question this can be checked out for you.

Yes my TV is freeview hd and my I can't get HD channels at all . Because the quality is so low . So 60% quality is OK then . It breaks up sometimes

hector : Well, although 60% quality cannot really be said as being ideal, it can however be perfectly OK on many devices provided that its observed to be completely stable if monitored over a minute or so, 80% + quality being a far more desirable level and with the signal strength usually lagging slightly under this.
If you have positively verified that your TV is indeed fitted with a DVB-T2 tuner? then its unusual "not" to be receiving anything at all on HD, therefore in order to get a better idea as to the cause of the problem maybe you could provide your location, this preferably being in the form of a post code or one from somewhere nearby, e.g: a shop / Post Office, plus also a run down on the aerial system you are using.
