When we traded in our Berkshire I elected to transfer our RFMogul dish (Direct TV) to the Anthem thinking I'd save a few dollars. Wrong. The installer in Texas didn't know what he was doing so $500 down the drain. Stopped in Salt Lake at the manufacturer and they found the problem, a splitter installed before the interface box, another $400. They didn't do coach wiring at the factory so I had my home installer remove the splitter and then follow up to make sure we had a signal on all 4 TV's. We ended up having to run a new HDMI cable to the front overhead tv as someone somewhere had pulled the end off at the splitter in the basement. He also installed an articulating mount for the outside tv. Another $900 but the RFMogul works perfectly and we don't have to recalibrate, at least not yet.
Just thought I'd let everyone know there are options out there.
