Sounds real simple doesn't it?? Want me to tell you how mine is REALLY wired. I assume the UDC you speak of is where all the wires are connected, and the Cable TV part of what you say is true, HOWEVER when it comes to the satellite connections here it is. The LNB cable comes from the roof as you said. one for the living room and one for the bedroom. One coax cable leaves the panel and goes to the living room. I have been using this one since we bought it. There are THREE cables left that could be the bedroom. After trying every tool I have to trace those cables, I decided to just pull another one in as Joy and Jeff explained in their post. Bad choice. Heartland bundles their wiring and puts them inside a sleeve that is split for the entire length. If the fish tape gets outside the sleeve it can go anywhere. There are no conduits per se and the tunnels in the insulation are FULL. I could not get a fish tape from the bedroom TV location to the lower storage area. In the process I did find my problem. I kept noticing the wires followed water lines through the storage area and there is a plumbing connection for a washer dryer in the closet in the bedroom. When I accessed the service door, there were two cables there that had been looped through, cut and spliced. When I traced them with a tone one of them went to the storage area. I thought about running a short jumper from this to the TV mount. With the cable problem almost solved I thought about working on another problem. There are two speakers in the ceiling in front of the TV that have an on off switch on the wall near the light switch. These have never worked either and I often wondered why they would put switches inline with a speaker so I accessed both the switches and the speakers. When I removed the first speaker, guess what....there was a coax cable cut and stowed in the speaker mount. I toned it out and both sides of the cable went to the washer dryer area. Now all I have to do is run about 2 ft. of wire from the speaker to the TV booster access hole. I still have not found the other end of the cable coming out of the TV junction box that was designated as Satellite.
