A customer of ours put a 2 story addition on their building. We did the wiring for voce, data and SAT tv. SAT has a RG6 quad sheild home run from dish to basement. Another RG6 QS home run from basement to second floor to connect to SAT equipment. Direct TV is the provider. Every thing worked fine for about 5 months and then just quits. Direct TV comes out and says the problem is with the wiring. I go out, break the connection in the basement and meter out the cable form second floor to the basement, its shorted. Replace the F connectors, still shorted. Run new RG6 QS. Still not getting signal from the dish. Direct TV comes out and says the new cable will work but will fail again because it does not have a solid copper center conductor. That when you change chanels the converter sends a signal, with 13 to 18 volts to the dish and over time this voltage will cause the copper clad center conductor to fail (melt??)
Does this sound correct?

Its got me baffled. Thanks,
Steve
