I have an old Primestar dish that had its LNB replaced with a Dish
Network one when I subscribed to that service. I dropped Dish a few
years ago, but now want to use that dish for Ku signals (and using a H-H
mount). However, I want to keep the DISH LNB to pick up the occasional
FTA circular polarity signals as well (like their music channels).

What is the best way to mount 2 LNBs on a dish - both the DISH one and a
KU one? (I will obviously be using a Diseqc switch to select them.) I'm
concerned that they both accurately point to the focal spot/sweet
spot/whatever you want to call it, so that when I point to a satellite,
*BOTH* LNBs give their best possible signal without needing minor
corrections east or west.

The focal point is the size of a golf ball, there is no way that both
feedhorns can be at this point at the same time.

You CAN pick up more than one sat on the P* dish.
