I live in the caribbean and have a 6 foot satellite dish. i have an account with dish network. I just bought a new 722vip dvr receiver, a dish pro dual lnbf and a dp34 switch on ebay. I have used a single lnb with an old dvr dish tv receiver for years and it works great. wanted a new dvr. i need to know if i can use the dual lnbf on the big 6 foot dish. i don't care if i only get sat 119 but would be great to see if i can get both sats. i know the dish tv dishes have a special shape to pick up the two sats on one dish but I only have the big dish on my roof. it is needed to pick up the satellites from the caribbean. any help would be greatful
