Hi Guys
A good explanation there Woodentop but may I just add a few points.
He doesn't need to pay a second subscription to receive all the premium channels he enjoys at home.
He can take his home Sky box complete with the card and pretty well use anywhere in the UK and parts of Europe where a Sky signal is obtainable . One of the links below will show him the availability.
If he chooses not to use his home box he can remove the card and place into a spare Sky box and take that. My own experience of doing this is varied. Sometimes it works perfectly other times I've had to ring Sky to get the temporary box and "master " card synchronised.
Over the years I found it far simpler just to take the complete home box. I've prewired the caravan and am slightly ashamed to say we have tv in the bedroom and lounge of our tourer. Disconnecting the box at home takes less than 60 seconds.
I'd suggest to anyone following your advice to consider buying a Sky + box from the places you mention. This will enable them to record and view already recorded stuff or other Sky channels like his football.
I agree about the dish. For 12 years now I have used a Maxview 66cm semi eliptic dish with a 4 outlet LNB. A 2 outlet will also suit the OP.
Tuning wise I have tried lots of things .
1. See if anyone else is using a dish.
2.Get a sat finder app for your mobile phone.
3. Buy a half decent sat finder which you quick release wire direct to the LNB. The search screen will usually give you the skew angle , azimuth ( angle of elevation ) and the compass direction in degs.
I use the Primesat SF500 with great success and thanks to my old mucker

I hope some of this combined with Woodentops suggestions works for you
