[QUOTE="spiney, post: 161999, member: 192438"] I don't see how it could possibly be "more efficient"! The "aperture" of a sat antenna - how much signal it can collect, and then focus on the lnb horn - can be no greater than the lens or dish cross sectional area. Anything else just isn't physics. It would be nice if somebody found a way to get a big signal from a small dish, but there's just the tiny snag that it's impossible (if you could do that, then somebody else would have, ages ago!). Presumably, the lens special design makes it easier to "space" several different lnbs, which would seem to be the point, but the local field strength for each one must still be fairly high. (It would be nice if they gave actual performance (gain) figures!). [/QUOTE]
