NanoVNA: Testing Coax For Characteristic Impedance And Distance To Fault (Length)

NanoVNA: Testing Coax For Characteristic Impedance And Distance To Fault (Length) is my attempt to simplify and demystify some the the cool things you can test on transmission line with the NanoVNA. This is just one of a group of videos I'm doing on this amazing little tool. For most of us in the Amateur Radio Hobby, every new thing we do brings forward all sorts of learning and experimentation. This is just one video I am making in this journey of discovery! If you want to purchase the NanoVNA shown in the video, it's available on Amazon Prime here: https://amzn.to/3t9zsB2 And of you are trying to get the majority of the adaptors you need to run tests on different devices, here is a good kit. I wish I had found this when I was digging up all the stuff I needed for testing. You probably will want to buy at least two of these to get setup for both sides: https://amzn.to/3J8sBxq.
