Reception problems

Why does the picture break up or freeze?

With digital terrestrial, if you have a poor aerial the picture tends to freeze, stagger or break up into little squares. Also you might get some channels perfectly and others not.

Your rooftop aerial could have been blown out of position by the wind and need re-orientating, or the down-lead might need replacing if it is corroded or waterlogged. Or you may need to replace the existing aerial for a better one or one that covers all the digital frequencies. Your local registered aerial installer will be able to advise. See above for help with indoor aerial problems.
