I have a 2008 3400RE Bighorn.
It has a coaxial cable from the UDC to the entertainment system in the livingroom.
It has a coaixial cable from the entertainment system in the living room to the bedroom.
I cut the coaixial cable running between the livingroom and bedroom and put connectors on each end where the cable was cut.
I disconnected the second coaixial cable that goes to the length of coaix in the ceiling in the bedroom for an outdoor dish on the roof and coiled it up in the basement behind the UDC for future use.
I connected a length of coaix from the split cable in the livingroom and connected it to the connector in the UDC that was for the coiax in the ceiling.
I installed a coiax connector in the UDC and ran a cable to the coaix that was split going to the bedroom.
I connected a cable to the extra connector in the livingroom, where it went to the bedroom, to the DVR. This is now going to the UDC where the second Satellite to the bedroom ceiling was connected.
I no longer have a receiver or TV in the bedroom. We normally do not watch TV in the Bedroom, but if I had a receiver and TV there I could make the connection from the extra connector in the UDC.
I run a dual cable from the Satellite to the UDC and it runs to both of the connectors in the entertainment area anc connects to the DVR.
If you want to see cable in the bedroom connect one of the cables to the new cable connector in the UDC. This may effect your DVR because it should be setup for two cables.
If you want to keep a receiver connected in the bedroom and the two in the livingroom you might try one of these.
I used it until my receiver in the bedroom died and the TV needed a box to convert it from analog to digital.
