Hi. I have had sky for 5 years on my boat. first i was told by sky that it was not possible because i did not have a land line, but i put forward the point that not everyone had a land line. After a few calls they told me i would have to pay £25 connection charge which i did, no problems. Last year i upgraded to Sky+ which they would send an engineer to fit, as i had wired up the twin leads to the lmb all he did was fit the new lmb and tune it in. Again no problems. When i go out on the boat it takes me no longer than 5 minutes to tune it in.
