nanoVNA - Coaxial Cable Characteristic Impedance Measurement Methods - Testing 75 Ohm Coax - VE6WGM

1. Testing the methods described in the previous video to measure coax cable characteristic impedance using the nanoVNA... this time on 75 ohm coax cable. 2. How to measure coax cable length and impedance using time domain reflectometry. (Begins at 4:56) Reference: Reflections of signals on conducting lines & phase change: https://en.m.wikipedia.org/wiki/Refle... Mistake: At 0:28 in this video I noticed that I pointed to the 180° S11 phase point displayed on the nanoVNA and was talking about staying away from the resonant point. Well, for whatever reason, every so often I seem to mix up the S11 phase graph and the Reactance (X) graphs... and I'm sure that this is not the only place in my videos that I 've done this, LOL! So, if that was the reactance graph it would be correct. My apologies. I will be watching for this mistake more closely in future videos...
