My Winegard Road Trip Dome can be switched to Dish network but it is only a 12 inch elliptical dish and these just do not work down here in Mexico. January 2011, I could get DTV in Ensenada, but further south than that, no signal at all. Other coaches with 60cm roof dishes could get signal as far as Guerro Negro. Shaw uses a different system, and the foot print extends over Mexico, as far south as Puerto Vallarta!!! The new Explorer SD 75cm dish works well here, as will any portable 75cm dish, with Shaw/Starchoice. With a 60cm dish, you will have some HD channels drop off.
