M88, the LNA is the piece that sticks out in front of the dish right? (sorry i sound stupid, lol). I know there is a cover on the bottom of the cast, but I couldn't get into the ones I have because their all epoxied shut, so i just threw them in the bucket. I'm guessing this is where the board is?

And no, the dish companies don't reuse them, at least not around me anyway. I think people just keep them "in case theirs breaks"
