enb141 Even if you get one of those you will still need to find the way how to mount it on the lower feedarm. Could you show some pictures of your antenna and all the spares it has? Only the first feedhorn from your previous post can fit to an offset dish, the second one is for PFA. So, original CM feedhorn will cost you ~100 bucks, flange LNB may cost ~30 bucks, plus delivery that will cost you ~200 bucks. To fix LNB to the feedarm you will need special metal frame, which looks like this If you do not have it in the set, then you need to get it somewhere or DIY. And, again, IMHO it is much easier to mount simple universal LNB like IBU and get pretty much the same reception results.
