And Stargazer, to guard against any possible misunderstanding, let me state that my above post wasn't intended to be making fun of your suggestion, as some will surely believe. That is a very interesting idea, one that's never occurred to me. As I point out at the end of the above post, though, a magnifying glass, per say, will likely reduce or block the signal. However, I still do think it's a great idea. I'm sure some of the physics behind the magnifying glass could be applied to a different material in some manner to achive an interesting signal focusing effect (without simply reproducing the dish reflective focusing effect).
(...if anything, my earlier suggestion of trying the LNB directly pointed toward the satellite, without reflector, should be scoffed at)
