Coaxial Cable

Coaxial cable does in fact produce small, non-linear phase shifts and reflections that vary with frequency, even when properly terminated. This is due, I believe, to variations in physical tolerances along its length and perhaps also chemical makeup. I have measured these anomalies in the past, and while they are insignificant for most purposes, a sensitive nulling mechanism with a dynamic range exceeding 60dB or so can detect the effect of these disturbances as variations in input impedance.
