I recently moved into a new house and it only had a SD dish so I had dish come out and install a new HD dish. Everything works fine with the home system. I use a 211k receiver in the house and I also use that same reciever for my Dish Tailgater that I use in my RV. When I hooked up the Tailgater it does not work. No setup page for location ie states. All I get is searching for signal and it does not find one. It's almost like ther rec I have tried check switch and replaced the coax. My question is, could the Installer have changed something when he installed the new home HD dish that would have made my Tailgater no longer work?
