George:
I'll probably wish I hadn't jumped in here but here goes:
We started with Dish. Needed two LNB's to receive the 110 and 119 Sats simultaneously. Needed switches to feed two sats to one receiver. Later added a second receiver for a second TV without any more switches. In other words if I understand the system the dual Sats created the need for LNB's and switches.
Switched to Direct. One Sat, no switches, two receivers so we can watch two TV's on different channels.
