You can use a Phase III with a Dish Network receiver but will only pickup one orbital satellite slot at a time with the lnbf that it comes with.
You can saw off the arm where it gets wider that holds the lnbf and drill a hole in it and put a Y adapter on it and get two orbital slots, you can get three orbital slots by strapping an eye to the side of the lnbf on the Y plastic bracket or placing the twin on the Y bracket with half of it hanging off of the Y bracket (119 side of the twin on the 110 part of the Y bracket) that way you will not have to strap the lnbf on, less work that way.
It worked for me and a friend as a poor man's Dish1000.
