VHF UHF Moxon Antennas

Nice model very portable, managed a good SWR on the 2m even only about 2m from the ground, should be much better with a telescopic pole I ordered.
Super easy to print and assemble, the guides for the lines kinda check if all your wire sizes are correct so not much can go wrong (unless you spend too much time soldering the connector).
Really love the pole adapter, loaded it into fusion and made several sizes for the different poles, the photo is just using leftover pvc pipe from the construction.
Printed in PETG no issues at all.

Hi, I've printed the 70cm first and the resonance is at 380Mhz for me with a second resonance at 420, at the center 435Mhz the SWR is 2.4ish.
Trying to diagnose what's wrong since your own build had a much lower SWR, I found a issue with the description where it references the wire is 22AWG or 0.5mm2, but 0.5mm2 is about 20AWG, I've tried with 22AWG and solid core 0.5mm2 and have gotten similar results (resonance too low).
What is the correct wire size you used? Also the wire from the video fits very well in the holes, while I had to enlarge mine a bit to fit 22AWG (about 0.32mm2) this could be due to the isolation thickness or it could be the wire is thinner?
At the moment I only have 2 other things to chase:
1. Material used for the print I used Grey PETG and on your video it's black I think some companies use carbon for black which could influence the antenna.
2. The wire used, thickness plays a part but also the isolation changes the speed factor which changes the sizes of the antenna.
Any ideas to point me in the right direction would be appreciated, it's a nice model, I'm about to build the 2m one I'll post my results once I have them.

I have not come across PVC tube that narrow before in Canada. Would carbon fiber tube work?

The 70cms version is to big for the Flashforge printer. The bed is 22x22cms. Is it possible to make it more compact? For instance, a snap in so it can get printed and taken apart so it can be printed with a Flashforge.

Easy to build and print. Works very well had to print my own 10mm tubes https://www.printables.com/model/1252145-tubes-for-moxon-antenna
These were to big for my printer so I cut them in half and used glue and couplers, uploaded the file here if you need to do the same: https://www.printables.com/model/1392861-2m-moxon-tubes-for-smaller-printers

The 70 cm moxon has a very high SWR, and is resonant at approximately 350 MHz

Swr is perfect, 1:11

Can anybody tell me the size of his 70cm Moxon sonI can compare it? Mine seems to be too large as it is resonant at around 350MHz.
Thank you in advance. (edited)

mayor update on the original one https://youtu.be/J44nEcISGXU

I printed the parts in PETG on my Bambu P1S, and designed and printed my own tubes, as the specified tubes are surprisingly expensive in Canada. I've shared the tubes as a remix.

I've been using the Moxon in vertical polarization on a fishing pole for early testing.
