I thought a BUD was something like a 5+ foot diameter dish. Please quantify BUD for me.
That's what the input port is for - another satellite.
And port 4 will only work with a Dishpro LNB.
Absolutely not. What led you to think that? Not that it's unfathomable, and it could make some things a bit simpler if the switch had an integrated diplexer, but it doesn't follow from what you've been told. Seriously, what was the source? The answers you've gotten here have been correct.Upon doing a little investigation it seems I could also connect an OTA antenna to it.... is this correct?
