I have had success with all dish network dishes i have experimented with to receiver fta signals. I receive everything on 97w with about a 60% Q on my wetek play 2 if im pointed directly at 97w. It drops about 10% if i point one lnbf at 103w and place a second lnbf at 97w. I have had minimal success with a third lnbf pointing at 87w. I only pick up the patient channel and the MTA mux, and only using a dishnetwork turbohd dish not a dish 500. The Dish 500 will do 97w and 103w fine though. Its also important to mention neither dish will receive any pbs mux at all. Was hoping they would but even pointed directly at 87w or 125w no pbs with the exception of 125w does now receive montana pbs (assume its due to recent power increase). IM attaching photos of my first attempt at small dish useage with the results using a sathawk pro receiver. the 3 satellites i was receiving were 91w 97w and 103w with 103w being the main lnbf.
That's pretty cool on your setup especially getting Cozi on 103. Going to try the same with an old Dish500, and Directv slimline no longer in use. The tough part is making the custom LNBF holders. PBS can be a tough nut, so sticking with a 90cm is the way to go.
