I am a long-term and existing directv customer...., and current have 5 receivers set up with a terk 5x8 multiswitch that is powered. Some cable runs are about 100', but no longer.... HD locals are now in colorado, and I have ordered for install the new AT9 dish, and the H20 receiver that will plan on using on only one of the 5 TV's for now, and using the existing (and older equipment/receivers that I still currently have). I realize that I will need the H20 receiver to receive the HD local broadcasts.., but my questions are: - will my existing and older directv receivers work fine with the AT9 dish AND the zinwell 6x8 multiswitch (knowing I will not get the local HD broadcasts with the older receivers), or are the new (H20) receivers necessary on all TV's when you get the new dish? -What about my current HD receiver (Sony HD 200 receiver) - will I still get HD signals, but just not the local HD broadcasts? -since the zinwell 6x8 multiswitch is not powered (as opposed to my existing terk multiswitch which is powered), should I anticpate any signal problems with the couple of cable runs that I have that are around 100 ft long. -I don't think I have the solid copper (or recommended RG6 cable), but not sure. If I don't, the last thing I want to do is rewire the entire house and cabling. Will I be ok if I do not have the recommended RG6 cable for the new dish? -my current phase III dish is firmly mounted on the side of my house, and there is sufficient room for the AT9 dish. I want to mount the AT 9 dish is the same place on the side of the house. Some installs here I saw are on top of a roof, with additonal support. Any foreseen problems if I mounth the new dish on the side of the house knowing it is a secure location for at least the current phase III dish. -As a side note, I purchased the Sone HD200 receiver a few years back for about $700 to get the HD broadcasts. Now, you can get the HD20 for next to nothing. What a joke...., I just hope I can at least still use the Sony on another HD TV for the time being (again, w/o the local HD broadcasts). Thanks in advance, and certainly appreciate any input before the install coming up.
