Okay, once and for all:
The ONLY lines in satellite that can be split are those carrying pure feed. NO splitters between the switch and the receivers.
1. 13/18VDC lines CAN be split, but ONLY if ONE power source is used and ONLY if the power level stays at that level such that it is kept on either left or right polarity. An example would be splitting the legacy 110 and 119 outputs to feed multiple switches or building what is euphamistically referred to as a "homemade 64".
2. Dish Pro lines CAN be split, but ONLY between the LNB assembly and the switches. Such as splitting the output of a twin to feed two or more chains of cascaded DP-34s.
Other than that, no. Splitters are for distribution from source to switches. Past that, DBS is a switched system and each receiver needs its own switch port dedicated to it.
There's such thing as transcoding from QPSK to QAM and putting a digital receiver at the far end which acts like a digital cable box and those lines can be split because they act like digital cable, but unless you're building your own private cable system and can afford thousands, it's not an option for you.
