Maybe my brain isn't working well this early, WT? The OP has a Hopper and 3 Joeys. He has what appears to be a single node. He's got 2 coaxes coming from the dish to the node. If he changes the single node to a duo he's going to need a 3rd coax from the dish anyway. So, all he needs to do is add that third coax and attach it to the 211 to keep it authorized.... Am I missing something? Someone already suggested that the third coax could be added for about $50 by Dish and that's a good thought. Our OP doesn't want to ad the coax himself because the dish is up on the roof and he doesn't want to go there....
