Mike Hahn: Every transmitter in the UK (over 1000+ of them) broadcasts HD channels. BBC News HD is on the temporary COM7 multiplex which is available (along with COM8) from 30 main transmitters covering around 70% of UK households and will not be added to any further transmitters and is expected to close in 2022. Depending on your exact location (please provide a full postcode) you may be able to receive COM7 from another transmitter (e.g. Crystal Palace). Alternatively BBC News HD (and all of the BBC's other HD channels) are available free to air on satellite, or online via iPlayer.

Alan Batchelor :
Which channels are you getting the pixelation on?
You are predicted to get good coverage of all multiplexes from Hemel Hempstead, however, if you have become inadvertently tuned to any multiplexes from Crystal Palace, you won't get as good a signal if your aerial is set for Hemel Hempstead. Are the rods on your aerial vertical or horizontal?
Also, it would be worth you checking all your coax plugs, connections, flyleads etc, unplug connectors check for corrosion or other problems and reconnect them. See what signal strengths and quality you are getting for the multiplexes shown in your TV's tuning section, this may indicate any problems with your aerial or downlead. Also check that your downlead looks undamaged and that your aerial seems intact and pointing in the correct direction.
Problematic connections, water ingress etc. can seem to affect reception of just an individual or several multiplexes.
