The real reason that photons are not a particularly useful concept in RF
design is that they are vanishingly small in energy, due to the rather
long wavelenths. I doubt if there is any equipment that would actually
intercept a MEASURABLE photon at most radio frequencies. You cannot
always say that of short-wavelength gamma rays or even light.

Yeah. And, photons like razor edges, with a passion! ROFLOL!
