I have a dish 500 and a 300. I need the 61.5,119,110 signals. Do I have to have 2 seperate dishes to get these signals? Will a dishpro twin dual plug into the switch or do I need 2 singles dishpro lnbs to plug into switch. I currently have 1 dishpro lnb. I tried to hook 2 legacy lnbs up to a 34 switch at first but then I read that legacy wouldn't work with DP. What do I need to do? Thanks btw I also have an 811 and 508 if this matters.
