Video: how to measure the velocity factor and impedance of unknown coax

[w2aew]

I picked up a nice chunk of high-temperature coax cable this weekend, and wanted to determine the impedance and velocity factor of it.  Here's a video of how I did it.  *Please* pardon the bonehead  decimal point slip in the metric conversion    Enjoy!

Awesome educational video, Alan.  Yet another in a long line of great content videos.

Are you stalking me?

The number of times your video's coincide with something I need to know or do is incredible. Thank you heaps for your time, creating these

LOL!  Let me know next time you have a need to know something - maybe I'll already have a video queued up!

  Another handy video. Thanks.
Don't want to discourage you from providing metric measurements but 29 feet is nearer 884cm.

Yes, of course it is.  I've already added "annotations" to the video to correct my error in the metric units.  Bonehead error - sorry about that

take it easy it might happen to anyone who is not used to metric
the most important and interesting part is sharing your knowledge  . hats off to you for that !
