My setup for me to get satellite 129 is to use a Dish 500 with a single LNB. I have a Dish 1000.2 antenna with the 129 LNB covered and using it for 110, 119. I have no problem with signal with the 1000.2, but the Dish 500 only pulls a signal between 57 and 64. I have an extra Dish 1000.2 with all the hardware /parts, plus the three LNB(s). What I would like to do and if it would benefit me to install the 1000.2 and use a single LNB. Can that be done, and would my signal increase? I might have to modify the LNB arm so it would except the single LNB. Has anyone install such as I suggested?
