[QUOTE="dxsat, post: 446939, member: 193607"] Keano, Sorry to hear results weren't impressive with the Andrew Feedhorn on your dish. I've tried loads of LNBs with this feed and the Quad performs very much better than the single Invacom -on low band. I have never tried to pull in weak high band as you're trying to do. You may find a new quad will be better as LNBs, even Invacom, get a bit 'tired' after a couple of years. Many times I found reversing the black rings gives significant gain improvement. The arrow pointing to antenna is reversed so it is pointing to LNB, move whole assembly away from dish. The small Andrew feed in the last pics is tight back against the holder, so the focal length of the dish may be slightly long for the feed. I guess you have tried changing skew, high band is very sensitive to skew errors. In the pic of the whole dish it looks like you have a tree or shrub in front of it, ?? [/QUOTE]
