High SWR? - Let's Investigate!

I investigate my 1/4 wave vertical antenna & feedline after the SWR unexpectedly goes sky-high. I was sure that I had it all figured out until I carried out a final test to confirm what I thought & the result left me totally confused!!! I run the channel on a non-profit basis for my own enjoyment & (hopefully) to benefit the ham radio community. I fully intend for my videos to be free for everyone to watch and therefore I don't have Patreon or other membership schemes. If you do want to help support the channel you can "buy me a coffee" using the link below:- www.buymeacoffee.com/hamradioonline All funds raised will be put back into the channel (upgrading camera/audio equipment, travel costs to film content etc)
