In a single LNB, single receiver system, you can watch a single channel
on multiple Tvs, if you have cabled from your receiver to each TV. It
is not possible to watch different channels with this system. To watch
different channels you need DUAL LNB's for C and DUAL LNB's for KU.
You will also need a separate receiver for each location, and a fairly
complex means of splitting and distributing the incoming cables. It
can be done, cable companies do it all the time, but it is probably not
worth the effort, especially if you want to view subscription channels
because the bad news is you will need to pay another subscription for
EACH LOCATION. That can be expensive. However, having at least two
receivers is not a bad idea, and fairly easy to do. However, you can
only watch signals on ONE satellite at a time doing this. One alternative
is to RECORD programs ahead of time for viewing by others in the family.
In this case having a couple of receivers, a couple VCR's and splitting
subscription channels between the two will let you build up a nice
collection of tapes in no time. Once the family is really sold on the
dish, it will not be hard to convince them you need ANOTHER one. Or two or
three.
