taking the dish
Someone does not have a life here. I'd bet it's probably someone in the HOA. It's probably the only you'd wish bees/wasp would nest in the arm. I'd try to set up one of those mini-cams you see in the store.
I have went to a couple upgrades where they did have a splitter splitting to two different receivers with old 59 and it worked for years. THen I come out and add a different receiver or equipment and its ends up being a total rerun of the house.
reman
I'm sure the LNBF was defective and not because it was remanufactured. I install a lot of reman equipment and sometimes it runs better than the original. It's cool gave you an extra one, hopefully it works.
