Unicable LNBs and motorised dishes
A Unicable LNB is a technology which allows multiple users (or multiple tuners) to access satellite broadcasts over a single coaxial cable and eliminates the need for the numerous cables required by a conventional system. In order to satisfy all users of the system the dish must remain permanently orientated to the one satellite that all the users wish to receive programing from. If the dish were to move from its permanent orientation this would disturb the viewing of all users of the system.
A motorised dish, on the other hand, allows a single user to orientate the dish at will and access broadcasts from many satellites right across the geostationary arc. Because he is the sole user of the system the continual reorientation of the dish as he moves from one satellite to another will not disturb the viewing of other users as there aren't any.
Trying to mix these two technologies will only end up producing unsatisfactory results. When multiple users (or multiple tuners) need to access more than one satellite the correct hardware to use is a permanently orientated dish with multiple LNBs or multiple dishes. This will ensure the viewing of one user does not disturb the viewing of other users of the system and also zapping will be instantaneous. This multi-sat system may use specially programmed Unicable LNBs and can still be delivered to multiple users over a single coaxial cable.
