The Mendip transmitter group relays are:

You are affected if you receive your TV signal through your aerial from the Mendip transmitter group

If you receive your TV signal through an aerial and are watching the Mendip transmitter Group you will be affected from the first date. It is possible that your aerial may be pointing towards a different transmitter group that will switch at another time. Please see the map for more information.

The digital TV switchover affects any TV not connected to a satellite service

The easiest way to check if a TV is affected is to look for the messages that will appear at the top of your TV screen several times a day. These will appear in the months before switchover and will run until the switchover is complete.

You won’t see these messages if you are already watching digital TV (e.g. Sky TV, Freeview or another) or if your aerial is pointing at another transmitter that will switch at a different time.
