Wow, How I missed the is, but it isn't thing in PR. I still have an old 3900 legacy receiver I can use down there until I see wtf I can and can't do. I can always EBAY a couple DP duals and install later. If I can use Dish mover, I might be able to use the LNBF's from the "new" 500 PR antenna if they are DP duals mounted on the yoke.
