When measurements don't fit in with everything we already know, real scientists and engineers are trained to ask themselves:

The question is simply: Is my HP-355 step-attenuator set intermittently off by 3db?

If you still cannot see that the potential sources of error in your "propagation experiment" were *vastly* more numerous and complicated than that, then this horse is dead.

NBS traceable step-attenuator A-B measurement is the gold standard of gain and loss determinations.
