When I installed the 1000.2 dish, I had my older Dish 500 converted to a single dual LNB to get 129. Knowing I would have some issues with the 129 LNB on the 1000.2, I made the following cover of the LNB. I cut a 8" circle out of a old auto tire inner tube. I also went into the wife's kitchen cabinet and stole some 2' of aluminum foil. Folded it four times(thickness) and cut me a 5" round pad to go between the LNB and the rubber inner tube. Took some super glue and applied to one side of the foil and inner tube. I wrapped the 8" circle inner tube and foil over the LNB and taken a tie strap and tighten the tie strap real tight, and added two more tie straps for security. Cut off the excess inner tube. I now have a very good looking cover on the LNB. My "check switch" shows I have 4 LNB's....110, 119, X, and 129.
However, my Dish 500 is getting some poor signals from 129, most all TP's are in the 25-35 signal strength range.
