2m Foldable Moxon

I made a lightweight packable 2m moxon. It weighs 3.9oz (111g). I plan on using this instead of a rollup jpole. Posting this here for inspiration and ideas for others.

Thank you Casey

…unfortunately somewhat out of fashion… here is a program to create the dimensions:

As one of the most un-fashion conscious people on radio, I confess to having Moxons for 2m, 4m and 6m. The 4 and 6 are demountable on a fibreglass X frame. I find them very useful. The 2m one is great for use with a HT, when running battery-saving 2.5w gives a nice strong signal.

If Moxons are un-fashionable - who cares!

It’s a great antenna. I have commercial ones from Par Electronics in the states for 6m and 2m and am in the process of testing a homemade 10m one in the garden - or I will be once the temps get back over zero again!

Fashion victim or simply old technology?

Don’t forget to account for velocity factor of the wire chosen to use. It will change the dimensions.

Thanks Ed for the calculator link. I’ve always like the moxon. I agree, it is a great antenna.

Clever design Casey
I like the Moxons, use them 4m-20m whilst campervan portable.
Very easy to setup and use.
Always a good feeling when using something home made.

Hmmmm…

Interesting mechanical design

I have tried 2m Moxons and while they work well enough I ran into issues

  • Robustness - SOTA gear needs to be unbreakable and my versions failed to survive. That might just be down to my engineering skills.
  • When used for vertical polarization the feed point is inconveniently placed for a nice cable routing
  • It really needs a balun at the feed point or the radiation pattern will be affected.

I ended up building a short-boom foldable 4-el Yagi instead but have only used that on one activation so far as a test - I will try it out on some of the more difficult VHF locations later in the year.

Cheers

Just by chance, I found a YouTube video from @OE5JFE with a clever solution for a horizontal polarized 2m Moxon that is foldable as well:

Thanks Stephan for bringing it up. That was one of my first experiments with 3D printing/design.
It works fine in general but it is still a bit fragile and I have not found time to make the folding mechanism a bit more robust. But I got some feedback by email of successful operation so it was worth sharing.

Definitely old technology… mine’s 2014 vintage and it looks like new. I adopted the design as it is easy to strap to the backpack and needs no on-site assembly.
