Hi there I am considering installing SKY at my hotel, I have been told by SKY that I need to purchase a box for each channel that I want to be viewed in each room. I have 30 rooms in total. Can anyone shed some light on how this can be done? Does it require more than one dish? How much cabling is involved, will it need to be run to each room? I ask because I would like to have some idea for when the installation is done. Thanks.
