Well, technically there is no such thing as a satellite splitter...
Since they finally figured out to separate the signal from different
birds, there is now no need to run a separate "channel" (read cable)
for like signals.  This means they can now use 1 cable for multiple
signals..  In the real world, we have had this for quite a while
(think QAM, but with much larger bandwidth)..

These are not really splitters, but more (multi) plexers...  Since the
signals are basic, the electronics in the multiplexers/de-multiplexers
are cheap and can be thrown into what looks like an analog splitter..
