I have acquired an extra Dish 500 with a Twin LNBF. The LNBF has 110 and 119 written on it. I know the use of this system is to connect to both 110 and 119, well can I take this extra items and hook up one LNBF and point the dish to 61.5? Or do I need to acquire a single Legacy LNBF to use? Thanks!!!
