4 degrees. I have a couple of those adaptors... I think P* used them when they got another satellite...and then they used them for the ku HITS system later...
I have a couple as well, courtesy of Stogie I'm going to put one up on 79/83 as soon as I can clear out space in the yard for a secondary dish farm. It's going next to my newly acquired CM 1M dish, which will be on 125w, and the Perfect 10 7.5' BUD. I'm going to replace the original Primestar "beer-can" LNBs with Eagle Aspen (Dish Network-rebranded) P870 stacked LNBs...
