[QUOTE="archive10, post: 1029934"] Disregarding the signal drop-off from off-setting your C-band LNB, the practical problem with the Channel Masters are that the feed-support arms will be in the way. The feed-arm design means that anything left or right of the central point has the feed-support arm right in front of it. Ways around this include doing a "Stuka", where you rotate the feed-support arms slight downwards, and attach an extension to the original bracket, and then attach the side-loaded LNBs to the central LNB. This has been done by several members (past and present) of this forum, so wait around for replies, or go check out some older threads. Another approach is doing a new feed-arm design (like [USER=312276]@RimaNTSS[/USER]), with a square feed-arms, and feed-support arms that attach much closer to the dish face than the original CM design. Effeciency depends on the mount and dish you have, and how much mechanical engineering prowess you have. I would try the Stuka first, then decider if worthwhile to try a new arms design... [/QUOTE]
