I had my 722 reciver replaced with hopper 2 in my motorhome, Dish installed a dish in the yard pointed 61.5 and 72.7 all works well. Now when I change the antenna lead to use my winegard on roof it does not work. I have a hybrid solo node (203952) that Dish installed on the east arc antenna in the yard. Do I need this on my setup? If so exactly how is it all connected? Thanks
