TWO Part video: Part 1 shows how to use the Transform function in the NanoVNA to measure coax length or distance to fault. Part 2 (starting at about 4:40) digs a bit deeper into the effects of a transmission line on the observed impedance and SWR, how this is represented on the Smith Chart, and some of the "magic" of quarter-wavelength long lines. I refer to a video on a T/R Switch that uses PIN Diodes and a 1/4 wavelength line:
