Television aerial

If you have the flying saucer type, it could be you are in a poor reception area. Try it in an area you know has a strong signal.

Most often I find that when my TV plays up its a cable connection issue. If you are in a strong signal area check connections into/ out of booster and cabling between this and TV. Try a direct fly lead you know is good and connect directly from booster to TV. Worth checking the input cable is tight and connected prior to this. 

 The flying saucer antennas are ommi directional so normally only good in strong signal areas, the newer type fitted to caravans are directional so more gain when pointed in the correct direction  and of course can be vertically or horizontally polarised to match the local transmitter. 

What you got there G6NYG, does GCHQ know?

Given the age of the caravan, is it a digital signal compatible aerial ? 

A quick look on "Tinterweb"  for its make and model may provide some answers.

Should make no difference Milo -- unless its  a  real  Ruff Ruff  one 

No such thing as a "digital" aerial. just misleading info to make you purchase a new one.

That's right but there are superior and inferior aerials being sold, some no better than a metal coat hanger.

There are also strong signal areas where that coat hanger performs with the best. However, those inferior aerials can be totally useless in my experience in the poor signal areas.  

There are plenty of people on CT who will show how dangerous a little knowledge can be. Digital signals as transmitted for UK television are weaker than the obsolete analogue signals we used to receive, at the same distance from the transmitter. That means that the old flying saucer shape may not perform well, where later designs of ‘log periodic’ with their directional array of prongs will work when pointing in the direction of the transmitter. Pitch your caravan close to a transmitter and anything, coat hanger, piece of wire etc will work. When you pitch further away, things will get more difficult and you may need all of the help that you can get - which leads to a ‘digital’ aerial, where the elements are optimally spaced for the frequencies used in digital transmissions, and pointed in the direction of the transmitter, will maximise your chances. Forget the technobabble and get a Status, or equivilant directional aerial, ideally with a signal strength indicator fitted. These are commonly referred to as ’digital’ because of their optimal design for digital transmissions. Close to a transmitter, as stated previously, a coat hanger will work.

But before splashing out on a retrofit, you might like to consider the flexibility of using an internet connected tablet for its diversity and range of programs available.
