Just curious. Are most LNBs compatible or proprietary? For example, say you have a dual on a Dish500 you used for getting intl on 61.5, could you turn it to some other sat (DirecTV, Voom, Sky, or other) and use the same LNB and their receiver to get service. I know the difference between a DBS and FSS LNB, but was just curious if certain satellite companies use proprietary LNBs. Thanks.
