There has got to be more to the "up to 20db of loss" rule for 90 degrees difference in polarization. I think they meant, up to 20db or else I dont think I would hear anything with my HT turned sideways, yet, I can still copy the signal, often with little difference, even on weak signals.

I am thinking it might have something to do with smaller wavelenghs the less signal will be received. Cross polarization has been used for decades for microwave links, like having 2 links in one, so there must be around -20db of attenuation here.
