I currently have a Dish 500 (110/119) and a single (61.5) connected to a 44 Switch I have 4 receivers hooked to the Switch - 722, 211, and (2) 612(s). I'm not seeing the new HD channels added this year, so I called and Dish stated I need the Eastern Arc. I also wanted to add (2) HD Solos and the Dish tech is here now to do the work. He's saying I will need (2) Eastern Arc dish(s) installed to feed the 6 receivers because the eastern arc has a switch built in. Is this true or is there another way?
