normally these portable type units can NOT be run through the coach's SAT INput since most RVs have at least one coax inline splitter, if not more, in the run of wiring - which causes problems with Satellite antenna signals. Running direct from the receiver to the Antenna with your coax cable is best, and I have run over 250' before with RG6 coax with no problems...
