So then I am better off with either the 1000.4 or 3 dishes? Is there a benefit to a 1000.4 and a third dish or is that only if I have any LOS issues. I used the dishpointer app on my phone an dfrom what I can tell the EA is wide open for all 2 birds if they use the same mounting positions as my current dishes. I am trying to avoid any more holes in my roof just because it is fairly new roof.
