First of all DISH Network was incorrect that that antenna will not work with their system. I have a Winegard RoadTrip Mission antenna that works with DISH Network and it was manufactured in July 2012. As a general rule any RoadTrip antenna produced after 06/2012 will work with DISH and some produced before that date will work. There is no way to tell exactly with out trying it out. As previously stated the Roadtrip will work with DirecTV in standard definition only. If you get a Wally receiver the first thing to do is to update the firmware using an open face 3 lnb antenna setup instead of trying to do it on your dome antenna.
