The easiest way is to get a STACKED LNB, a high pass 2-way and 2 high pass 8-ways. (5-2150mhz if I remember right) I used to work for a company that did DTV in MDU's and we would run an entire building with all the outlets activated with DTV signal doing it like this. You may need an amp with 16 outlets depending on your signal levels. As long as you aren't looking to put on HD or international stuff this is the easiest way to do it. PM me if you need help finding the parts.
