c/p from from R2 (a great lnb expert)
Basically, with the DishPro 1000.2 LNB, there's no need for an external switch if you are using 3 or less receivers... if you want 4 or more outputs, then a DP34 with external power assistance, for 3 sats, or... a DP44 for 4 sats, may be the ticket. DP44 is the way to go with this LNB.
Out of the box, this LNB is good for 3 sat's to 3 receivers, or 4 sats to 3 receivers if you connect a DishPro LNB to port 4.
