I'm in the Birmingham market, meaning we're coming up soon on locals in HD. my setup is like this: an H20 in the den, one RG6 line running to it. A D10 in my grandfather's bedroom, 1 RG6 run there, and a Tivo in my bedroom, with two RG6 lines. Each of these 4 lines run to a phase 3 dish. Will an upgrade to the AT9 with HD only at the existing spot require any additional runs of coax? The phase 3 is pole mounted in the front yard, will it be able to use the same pole? If I upgrade to the HD DVR when its released, will it require anything more than an additional RG6 run to the HDTV? Thanks in advance
