Hooked up king tailgater to dish receiver it would only bring in sat 110 after checking all connections and moving dish and doing many scans, I unhooked from trailer and brought coax in door. I hooked to receiver direct. All three sat came in great, I moved it back to the outside hookup, only 110 again. I think I will drill a hole behind tv and install a hookup on the outside and bypass all rv wiring
