Unicable LNBs and motorised dishes

A Unicable LNB lets multiple users (or tuners) access satellite broadcasts over a single coaxial cable, eliminating the many cables a conventional system needs. To satisfy all users, the dish must stay permanently aimed at the one satellite everyone wants — if it moved, it would disturb everyone's viewing.

A motorised dish, by contrast, lets a single user aim the dish at will and reach satellites right across the geostationary arc. Because he's the only user, continually re-aiming the dish won't disturb anyone else — there isn't anyone else.

Don't mix the two

Trying to combine these two technologies only produces unsatisfactory results. When multiple users or tuners need more than one satellite, the correct hardware is a permanently-oriented dish with multiple LNBs, or multiple dishes. That ensures one user's viewing doesn't disturb another's and makes zapping instantaneous. Such a multi-sat system can still use specially-programmed Unicable LNBs and be delivered to multiple users over a single coaxial cable.
