I currently have 1 942 in the house right now running 1 HD TV and 1 SD TV. I am thinking of upgrading to the 622. I know I will need a second dish 500 for 61.5, but my question is will I need a second run of coax from the new dish to the house or into the house, or not. I am not sure how this should be setup so I know if the installer is doing it right. Also I have read about a new 622 to be released, is it worth the wait. Any help is greatly appreciated.
