Well, since the original subject said LNB, not LNBF, and since the circular DBS signals are the only ones that would make this even remotely possible, I don't think it would work, because there isn't any such thing as a circular LNB. Ie the discussion of reversing polarity via receiver or reflection won't do anything for an LNB, which will have only a linear probe. Now with a circular LNBF, then yeah, that would be an issue. Still hard to believe that it would work. I sort of remember the post on the experiment, but wonder if it was somehow working as a freznel lens or whatever it's called, and however it's spelled, and somehow acting to give some gain. I've read posts from people who have held up a bare LNB at the focal point of a dish and gotten reception without a feedhorn, but I can't imagine there being enough gain even for the DBS sats if you just hold it up to the sky with no gain at all , and the previously mentioned fact that it wouldn't separate ANY other sats, let alone adjacent ones, makes me really skeptical that it's even worth trying.
