Hoping the installation mavens here can help this clueless newbie with an installation question. I'm installing a Dish 500 with 2 DishPro single LNBs. While aiming the dish, I connected the LNBs to the Y-bracket and the Y-bracket to the arm using friction only. All was well. When it was time to connect everything in final form, I could not get the Y-bracket connected to the Dish 500 arm. I inserted the supplied screw from the bottom of the Y-bracket and connected it to the supplied bolt on top of the Y-bracket. But even with everything nice and tight, there is *LOTS* of play where the Y-bracket connects to the Dish 500 arm. So much play that I'm worried that the LNBs will flop around in a brisk wind. Even worse, I've fiddled with it so much now that the indentation in the plastic for the bolt on the top of the Y-bracket is stripped. What am I doing wrong? If it's not me, is there a homebrew method to connect the Y-bracket to the arm on a Dishb 500 so that it doesn't move around? Paul Michael Brown Washington, D.C.
