Ugh, of course it turns out Yagi didn't invent it.

For the neurotypical folks, note that all antennas that look like this aren't Yagi. They might be a https://en.wikipedia.org/wiki/Log-periodic_antenna

or one of these… https://xkcd.com/466/

However, the name Yagi has become more familiar, while the name of Uda, who applied the idea in practice or established the conception through experiment, is often omitted. This appears to have been due to the fact that Yagi based his work on Uda's pre-announcement[5] and developed the principle of the absorption phenomenon Yagi had announced earlier.[8] Yagi filed a patent application in Japan on the new idea, without Uda's name in it, and later transferred the patent to the Marconi Company in the UK.[9] Incidentally, in the US, the patent was transferred to RCA Corporation.[10]

Ah, the intrigues....Like that blue LED guy. That was so sad!!! :( I felt super angry about that at the time.

And here's an old Instructable on building your own yagi for wifi: https://www.instructables.com/Easy-to-Build-WIFI-24GHz-Yagi-...

Pringles can based antennas were super popular when wardriving was a thing - https://www.makeuseof.com/tag/how-to-make-a-wifi-antenna-out...

Hey, if you could stay out of my browser history, that'd be great.

j/k, Yagi antenna are super neat, and I like seeing them.

I guess you mean it's some sort of great nerd challenge in school to comprehend and study this stuff. Taxing. Right? I didn't study EE so idk.

But if not...then you can just not read if you see it. Like a street sign to some place you don't wanna go: you see it, you turn the other way. Haha! :)

I think I miscommunicated here.

I was trying to say “this is an area I’m also interested in, and I’ve been looking into this recently, and I’m surprised to see it pop up here, because I thought it was niche.”

If you’ve got other stuff in the Yagi-antenna area of interest, I’d actually really like to see it!

Brings back terrible memories of taking Antenna Theory in grad school.

I enjoyed basic emag, but the equations for antenna operation are atrocious.

Atrocious how?
