Silly question, but if people are only using one satellite say astra and one receiver with duel FBC tuners why are the splitting the feed into the receiver rather than feed all tuners from the one cable.

I get splitting if you have multiple receivers, also get using the 2 inputs if you use 2 different satellites.

But really dont get splitting a unicable in 2 to put to inputs into the same receiver.

Am I missing something?
