Hi Brooke Maybe I'll drop a line to Hugo to get his comments.

At Ku band a wavelength is about 1 inch so the dish is 18 wavelengths across. But at GPS a wavelength is about 8 inches and so the dish is a little over 2 wavelengths across, a much broader (if any at all) pattern. Also I thought the signal from the satellites was circularly polarized, so bouncing it off a dish reverses the sense of the polarization. So I can't see how they are getting the huge signal strength improvement that's in the paper.
