I have just moved to a new house where analogue signals are not great so am arranging a rooftop ariel and am going to subscribe to Sky. Some questions I have as a first time sky,er ! 1)Do I need an analogue ariel - ie :will the sky dish receive all the current analogue channels as digital ones. Even if it does are there advantages in having analogue too ? 2)I am having an analogue tuner with my home cinema pack. Again reception is a problem. Will the sky dish receive radio and can I play it through the tuner (and record on a tape deck) ? 3)I have seen separate digiboxes for sale to receive free digital services at good prices, can these pick up all the sky channels if the right card is bought . Are any of these boxes better than those supplied by sky installers and if I got one would sky be interested in installing me an aerial and card only ? Thanks for any info.
