securing Televison in bedroom & connection questions

On televisions in RV's in the past 10 years that coax labeled SAT means you connect YOUR Sat receiver to that coax on the Sat input coax on the Sat receiver. The other Coax is from the roof top TV antenna. So, NO, the living room Sat box will not send the Sat signal to the Bedroom. Besides, very few Sat recievers now even have a COAX output for the TV. If you have a Reciever with a Coax ouput, you can rewire at the TV antenna booster to get the LR sat to go to the Bedroom thru the Roof Antenna coax. Doug
