I'm concerned about using an 18 inch Ku band satellite dish for GPS.
At Ku band a wavelength is about 1 inch so the dish is 18 wavelengths
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.
