Last weekend, I purchased a Sony Grand Wega(KDF-E42A10) to go in my bedroom. I have an installation for a H20 and an AT-9 dish in the morning. The tv and receiver are replacing older models that were being used. I also have a HDTivo and a R15 that will continue to be used in other rooms. With all of three rooms already wired for Directv, how long will it take to have the AT-9 dish installed? Will I need to use different cables running from the satellite dish to the receivers because of the AT-9 using the Ka and Ku band?
