>> putting your receiver in a metal box with the top removed solves the problem

No. Radio can turn around corners. It can also bounce off things. Radio is light, but at a much longer wavelength. It is less like blocking a laser and more akin to blocking out sound waves. Blocking line-of-sight to the transmitter would block the laser but would do little to block sound waves.

Yeah high frequency sound is a good analogy. Starlink is in the 11&40GHz region with wavelengths measured in cm which is about the equivalent to 20kHz.

The other really annoying thing about radio waves is that even relatively long wavelengths can leak through really narrow cracks (<1mm) if they are long enough (eg a wavelength) in the right polarization.

GPS is on 1575.42 and 1227.60 Mhz, though.

Isn't that above the critical frequency you'd get ionosphere reflection at? (Which makes sense, since the signals are coming from outside it at LEO)
