Winegard Travel'r trouble

I'm watching this posting closely because I just purchased an X2 Dish and Wally receiver and am also having issues with the 129 Satellite. I've set up and used the antenna in multiple areas, to include the west desert where I had a very clear southern view no trees, and low horizon. I can pick up the satellite with a short cable run through the window, but can only get 110 and 119 if I use anything over 50 feet total coax, try to use my Bighorns factory satellite feed in either the living room or bedroom. Again, both 110 and 119 work fine, just not 129. Even went so far as to build my own cables using high grade quad shield cable and quality connectors. Seems strange the other two sats show little to no loss of signal strength with the trailer wiring, or longer coax, just the 129
