What does this Antenna do?

Have you ever had an antenna and forgotten what it is for? Maybe you have been given one and wasn’t told exactly what it was used for.

I got given an antenna at at ham fest because it didn’t sell. Funny enough after I got it, many came to me very interested in it. I wasn’t sure what it did, but I could tell someone had put a lot of effort into it.



I had my theories as to what band it was resonate on, but I wanted to be sure. By just looking at it, it gave me many clues, like the length of the antenna, the length of the radials, the amount of radials, and how it was made.

Watch this video as I unlock my theory on what the antenna was made for. See if you can guess. Do you think I am right or wrong? Perhaps you have another theory or even know who made it. I would love to hear in the comments what you think.
