This is one of the easiest satellite locations to find, since the Astra 1 satellites transmit some of the strongest signals across Europe. The front face of the dish needs to be more or less vertical to find the signals (19.2E means that the satellites are co-located 19.2 degrees east of south). To find south, use a compass, or if you dont have one available, it is useful to know that the sun is due south at midday GMT (UTC). If you are in the UK, look due south and imagine this is "12 o'clock".
As demonstrated by the responses, seems they can point anywhere!
I am a navigator by proffession,and although used to the electronic compass, when stuck I could always do this click here .
Confabs suggestion that the Sun is south at miday is adequate for this purpose, though 'Noon' is actually when the sun crosses the meridian, i.e. rises in the morning, seems to stop for a milli second, then starts falling. This will vary with longitude, for every 1 degree from Greenwich(0 degrees) it will be 4 minutes later. Lands End is 5.7 degrees west so the time of noon would be about 24 minutes later, which is why lighting up times and sunset times differ. click here Believe it or not we are still trained to use a sextant and calculate our latitude accordingly.
Still, I suppose I must remember my map reading compass in the future whilst house hunting.
