Well the short answer is most likely "no".
If your rig is like mine;
The SAT cable goes directly from the outside connection to the wall plate with the amp button on it. No where else. You would need to run a wire from that wall plate SAT connection to the TV stand where your SAT receiver is located.
If you did NOT want to use the roof antenna or park cable TV at the TV stand, then you could buy a cable union to join the SAT wire off the back of the amp plate to the end of the wire that does go to your TV stand (also behind the plate but most likely on a splitter). You would have to remember where everything goes to put it all back when you could not use the satellite.
