Yes, that is how I keep track of the various International channel free previews that I list in my monthly threads, along with all of the other free previews.
You have the original style Plus dish LNB bracket, which is exactly like the one I use. The LNB for 118/119 goes in the center of the bracket, with a separate DP single (or dual, if you prefer) in each of the other slots, for 110 and 129. Could you post a picture of your 500+ LNB, to make sure you have the correct LNB to mount on that bracket?
