You would need a 2nd dish aimed at the 61.5 orbital slot.
Depending on your location the tech may need to set that up anyways for HD (If you are in say Philly or NE of there the HD is on the 2nd slot at 61.5)...
If you are getting Dish to receive sky angel, you should be aware that Sky Angel is not planning to be around on dish much longer as they are seeking to transfer their satellite transponder licenses to Dish network and get out of the DBS business. So don't invest in Dish equipment for Sky Angel alone, and expect that you will lose SA sooner rather than later.
sky angel plans to stop boradcasting via satellite. Unless you get a good deal on the dish, might want to ckip it. see sky angels website for more info and "disclaimer"
