What you want to do is fine. I have seperate dishes aas well. You'll need a 4(5) x 8
multiswitch. Make sure it's cascadable and can handle the 22khz signal sent from the receiver to switch between the 119 and 110 satellites. Also, if you're going to use a seperate, single dish for 101, I'd recommend upgrading to a larger dish (24" or 30") that will GREATLY reduce rain fade!
