I live in Omaha and I realize it will probably be another year until we get out locals in HD over the Sats. To be ready when the locals come on, I'll need the new AT9 dish and does it need special cabling? Does DirecTV cover the cost and installation for the new dish? How would I go about asking for the new dish? I also have a 5x8 multiswitch will I need a new one of those also?
