I have a Hopper with a hybrid 1000.2 antenna at my primary residence. I am installing a Wally at my mountain cabin. I have an older DP antenna with three heads that uses a double coax. I understand that the older DP antenna will work with the new equipment using just one of the coax cables. If true, that will save me buying an antenna. My question is---- can I replace the dual coax with a single coax and which one of the LNBs do I connect it too? Also, what about switches?. I plan on supplying only one TV in my cabin, so that should simplify things. How do I set this up?
