I got around the problem of feeding the signal from the LR to the BR by altering the wiring at the original amplifier/splitter. In my case the antenna splitter was located in the bedroom but the amplifier would keep the satellite signal from passing through to the BR receiver. I altered the wall plate by drilling and installing a barrel connector. The short black coax in the foreground is simply a jumper that interrupts the feed to the LR tv and when attached as shown completes the circuit normally, through the amplifier.
By unscrewing the black coax from the barrel connector I can attach the input to the DTV receiver in its place and bypass the amplifier. This allows me to use the built-in coax to bring the DTV signal from my living room to the bedroom receiver. Difficult for me to explain but I hope this makes sense.
