Building the N4CF 6-meter Moxon


You can build your own version of this Moxon. First a disclaimer: I didn't design it. I used the Moxon Calculator at http://www.tippete.net/cgi-bin/moxgen.pl to calculate the dimensions. Read this Wikipedia article to learn more about Moxon antennas.

This one is fairly easy to build. It uses an X-frame made of fiberglass spreader rods and nine 3D-printed parts:

The frame spreaders are 3/8" fiberglass electric fence posts from Tractor Supply, and probably other stores.

The Zip file also contains .stl files you can use to print your own parts from PETG material if you have a 3D printer and slicer software (or if you have a friend who does). If not, keep reading.

3D Parts Kit – $28.00

Buy these parts from me if you have no way to print them.

You get, clockwise from upper-right:

  • One central hub
  • Four spreader end caps
  • Two feed point insulators
  • Two wire end insulators

Version 2 – February 2024

I revised the parts design to include posts with holes at the top for the antenna wire, instead of holes for fiberglass pegs.

Working with fiberglass is nasty. The posts eliminate cutting 12 ¼" fiberglass pegs, and drilling holes in them for the antenna wire. No more fiberglass shards embedded in your fingers!

The price for Version 2 is the same $28.00. Just choose Version 1 or Version 2 from the drop-down list above the Buy Now button below.

A couple of notes about Version 2:

  • The 3D-printed posts are not as strong as fiberglass pegs used in V1 parts. This is not a problem in use, but take care while stringing the wire not to break a post.

  • Because of their tall posts, V2 parts come off the printer with more stringy "fuzz" than the V1 parts. I use a razor knife to clean-up the parts, but some "fuzz" might remain. It does not affect performance – if you're concerned about looks, you can trim it off.

No warranty! I chose PETG for these parts because of its claimed higher strength and resistance to UV light than the commonly used PLA material.

I built my Moxon in July 2022. The parts have held up well, but I don't know how long they will continue this good performance, or if they might break in high wind. Thus, no warranty.
