For those of you interested in home brew antennas, I just posted a blog about a 2 meter Moxon antenna that I built in 2021 that performed amazingly well and cost about $20 (probably more like $25-$30 today, not including the cost of a 3D printer). For those of you that are unfamiliar, Moxons are an ingenious, much simpler variation of the traditional Yagi. Enjoy!

Ah, the 3D printer!

I've seen designs for a folded Yagi. IIRC, the driven element and reflector were held in alignment using shrink tubing. I don't recall how the director was kept from swinging down. I don't see the article in my bookmarks, can't find it now - typical! I usually look in the plumbing aisle for my plastic parts.

Found the link -- it was in my bookmarks, which resemble an archeological dig somewhere in Mesopotamia.



IIRC, the main thing that kept me from building this was the need for a 40" piece of wire/rod, though since it's a reflector, it now occurs to me that I could make that from 2 pieces.
