YES , if you own a 622 and you want to add it you can. I added two that way and did my own dish 1000 install. Today I also changed back to a dish 500 for 110/119 sats and a dish 500 for 61.5. I now get great strengths in the mid to high 90s on 61.5 and in the 100s on the main 110/119 sats. I was struggling with strengths that flucuated hourly on the 129sat due to it being a peice of crap. Now I get all my hd locals from Houston because they are on the 110 sat and I get the HD CBS from New York because I' m eligible, on 61.5 . I'm in southeast Texas about 90 miles from Houston. Dish tried to get me to upgrade to a dish 1000 when I called but I said no thanks Had one and went back to 61.5 and I couldn't be happier. I would keep the 61.5 dish if I was you.
