Main Possible reasons to have your Freeview Channels: Have you had a  TV Aerial Installation done in the last 10 years? if not there is a chance your aerial is water damaged or has just deteriorated over time. Or have you changed the input on your TV to ‘ANTENNA‘, and tried to run a channel scan, you should be receiving at least some of your local channels. If this is not the case, the reason could be one of the following: There is not a clear line of sight to the broadcast towers or your cable has been damaged but if you are in the WF area then give TV Aerial Installation wakefield a call and we can check if there has been any work carried out on the Local Transmitter.
