I have a Dish Pro Plus 500 hooked up to a 211k receiver. It picks up 110/119 fine. What are my options to add the 129 satellite into the mix? I've got an old Dish 300 single lnb dish. Also got an old Dish 500 with the SW21 switches. Can I use any of this to add 129 to my setup? I know I can just buy a 1000.2 dish but I was hoping to save some money. Thanks.
