My parents travel 6 months of the year and need a dish 1000 for their RV so that they can take their 622 with them. They had an instal guy tell them all they need is a dp34 and another dish 1000. The problem is I don't see a dp34 on their house anywhere, I dont see a switch anywhere on their home installation. They just have one wire coming into a seperator behind their 622, thats all I could see. So why would he tell them they need a dp34 if there wasn't one here? I'm confused. On my istallation at my house they used a dp44 switch. Can anyone tell me what they need to travel with?
