Dish 300 is designed to be used with one lnb.
Other larger Dish Network dishes are detuned horizonally to cover 2 or 3 lnb's so they give you a false sense of better signal to be.
Another way is to buy a 30" single lnb designed dish like the Winegard DS2177.
Agree, the Dish 500 is not completely round, I think it's 20x22.
But in any event, I had 2 Dish 500s, back in 2007-2009 before eastern arc, With one at the 61.5, and the other 110/119.
And it worked fine.
Any Dish with a single LNB is going to work. The arm is designed to work with the reflector at dead center when zero out.
The LNBS and Skew are what makes the multiple orbital locations possible from a single dish.
You can point a 1000.2 at any one orbital location and it's the same as taking an 18 inch round dish.
Only issues, They probably don't make an adapter to have only a single LNB on the 1000.2 or .4 dishes.
