I live in mid Norfolk so am not near a transmitter. Worse, living in a bungalow means that the aerial is mounted fairly low. The result is that the signal disappears when there is heavy rain or high pressure weather.
I have fitted a signal amplifier in the loft. The wire from the roof mounted aerial travels down 10ft of wire then goes into the mains powered amplifier. It then continues to the television. This has reduced the blackouts by about 90%. But even with a new TV (January) the signal still cuts out occasionally.
Locally, we have been promised a stronger signal when the analogue transmitter shuts in November. Apparently the digital and analogue signals can interfere with each other. So, when analogue goes the digital signal strength will be increased.
I have fitted a satellite dish recently and get good reception of all the freeview channels. However, teletext doesn't work with my equipment and two of the BBC HD channels disappeared a few weeks ago with no apology or replacement. The satellite also gives me about 5 more film channels but the films are mostly rubbish and endlessly repeated. There are also half a dozen news channels which give a broader better view of world events if that is something you want. So it has been a mixed experience.
