Please offer the reason for focusing on a "DC Pulse" measurement of a single wire to analyze/predict the performance of that wire when radiating r-f energy. The r-f spectrum of a pure d-c waveform is zero hertz, so such a measurement tells nothing about the radiating capabilities a wire may have at radio frequencies. I have performed hundreds of d-c and r-f pulse tests of FM/TV broadcast antenna systems where the d-c resistance of the complete load including the antenna at the far end of the transmission line was 100 milliohms or less. Of course that produces a huge reflection in the time domain on the video display of a DC Pulse test set. However, when that system is tested at the operating frequency/channel using an r-f pulse having the same width as the d-c pulse, its performance is markedly different (see the pic below). These scope pics were made using the demodulated output of a directional coupler located at the source end of the transmission line. The incident pulse in the reflected condition is suppressed by orienting the coupler to its "reflected" setting.
