I have to tell you guys, I just switched dishes, (I had an old 18 inch dish), to an old Primestar dish, one of those really big ones. I put an old dish network LNB without its cover at its focus and tried to find a satellite. I used Lyngsat, ran the numbers, preset the dish, and all I can find with this thing is DN. I have found four satellites so far with 99 quality, but when I check them, they are all DN. Perhaps the focus is not good enough and the strongest satellite nearby dominates, I don't know. All I know is, I think I am going back to my 18 in dish. I had forgotten how hard it was to find something that wasn't Dish or DTV. Thank God I marked the old one before I moved it, and replaced it with this one. By the way, the old Primestar Dishes rock for signal strength, just have to tune them in. Trying for the G10R satellite, thought I would get less fade from the Primestar.
I took a c/ ku feed,with LINEAR lnb for C-band LINEAR lnb for Ku-band and added a circular lnb to the side of feed.All on a 10 foot dish.I love it,I have everything.
I have a Five foot dish, and may try it set up your way. I hadn't thought of the fact DN lnbs are circular and I had been using an old .8 lnb with a primestar feedhorn before. No wonder all I got was DN. Another Homer Simpson moment, DOH! I had the lnb and just used it without thinking. I used to install DTV and had a lot of old Dish stuff around. Not very useful, although the dishes work okay if you don't mind a little mod work. I used stuff at Lowes to make the mod on my dish and it works great.
