>>I think you're wrong, given that I worked with radar that measured rain effects using differential reflection of perpendicular polarizations of microwaves, and given the existence of the type of dual antenna with helixes wrapped in opposite directions (for two circular polarizations, apparently).<< One example there are many. C band Satellites transmit in 3.7 to 4.2 gigahertz band with adjacent transponders polarized opposed vertically or horizontally. With current 2 degree satellite spacing ideally each satellite's polarization scheme is also opposed to its adjacent satellite. I do not post often so do not expect a further response.
