For those of you wondering about hooking multiple receivers to a single port or even a dual port LNB, the answer is very easy. A splitter providing power through one leg is all that is needed. Whether it be a four port splitter serving 2 dual tuners, or an 8 way splitter serving 8 single tuners. A bandstacked single orbital would be easy, in fact, I dare say it would be easy as cable. One line from the dish. That line could be tapped multiple times as long as the final receiver was getting enough db and a clean signal to noise. Only one receiver would need to power the LNB and only one port at that. Now, once you add multiple slots in, then the install becomes as tricky as a normal "dishpro 500 install".
