I really think this could work, at the moment I however only have one dish (second one got dented while moving) so I can't really try it myself. I do not really think there will be timing errors since in the correct angle the dishes should be at an equal distance from the signal source, not when using an X structure atleast, but I could be wrong... I like the subreflector, but I think it will be hard towork out how to make one that will work and in what angle to put the LNB, gregorian dishes uses a parabolid but catches the signale at the same angle as the incoming signal, so we can't use that here, therefor I suggest a straight horn. I'm not really sure how one can go about simulating this kind of systems, but I guess there must be some simulation software, does anyone know of such?
I hope someone out there have time and equipment to test this.
