I am planning on buying a 721. I have Dish 500 with two receivers. I want to keep one and replace the other with the 721. As I undrestand it, the 721 requires two separate cables from the dish. What do I need to do this? Another switch? TIA
If your D500 has 2 dual LNBFs you can replace your SW-21 switches with a SW-64 as Chris suggests.
However, if you have the TWIN LNBF it is cheaper and easier to swap it for a QUAD. Some local dealers might let you "trade in" your TWIN for a QUAD. In fact, they might give you something for duals & SW-21s towards a QUAD, too.
