[QUOTE="Vipersan, post: 802834, member: 325666"] ..Thats the problem CH .. I'd say the basic design of the T is as close as I can get to perfect for Circular depolarisation.. Confirmed by others to give that 2 db gain ...as the claims of the servo motorised feed claims 3db gain ...this is indeed close .. The problem is that making a plate that doesn't require physical removal for Linear signals is as we know ..impossible ..so it would have to be a compromise. Thus a reduction in that 2db advantage on circular in favour or a couple of db gain on linear ...with the plate in situe. Now ..if only I can come up with remote controlled teleportation.. Press a button ..and it it vanishes from the lnb throat ...and materialises in my cupboard. ;) On a more plactical note ..I did wonder about the propeties of lcd .. A theoretical plate which remains in place ..and transparent with no voltage applied.. Apply a voltage and the plate becomes opaque ...(basically polarized itself) I wondered if this 'magical' dissappear and reappear act would actually affect signal polarity.. Perhaps not ...but it was just an idea ..and sadly I don't know the properties of such materials ...nor can I manufacture one in the back yard ..to test. Maybe not such a stretch of the imagination as light and radio waves are part of the same EM spectrum...just at opposite ends.. rgds VS [/QUOTE]
