If you don't have a 3D printer, your local library may have one or maker space will have one for sure. Just take the file in on a USB thumb drive.
-
Nice! I look forward to more videos of it in operation
-
Can't wait to see this one in action. Very cool!
-
This is totally rad!❤👍
-
Hi Michael. I look forward to seeing how well the antenna does for you. 73!

I have used a 20 meter Moxon four and a half feet off of my roof for three years now. I have worked on FT-8 all fifty states, 701 US counties, six continents and have confirmed 74 countries and 30 CQ zones. I should say my Moxon is in a fixed direction at about 70 degrees from Oregon. The Moxon is a great little Antenna.

I put a 2 meter Moxon to great use when we lived in a 3rd floor apartment. The j-pole I started with was radiating into the building. I found out when the downstairs neighbor started banging on his ceiling with a hammer. I was coming through on his clock radio and waking him up. So I got a couple of wooden lattice privacy screens, put them on either end of the balcony, and mounted a 2 meter Moxon inside one screen. It got into the local repeaters like gangbusters, and the neighbor stopped hearing it through his clock radio.

Very cool topic, video, and overall edit. Looking forward to your field day results video. Great stuff as usual. 73 w3rrm
-
Nice. I look forward to seeing it in action on field day. I hope to work you on 15.
-
Good luck with this one. Looks like a good performer for Field Day.
-
Very timely Michael. I actually bought the stuff to make this very same antenna last week. You and Chuck gave me a few ideas on how to do it better.
-
thank you.
-
Nice, hope you post a follow up video to talk about how it performed.
-
Good deal and great video! De WV1Q See you down the bands!!!
-
A properly designed and built Moxon should give much more than 9dB front-to-back ratio. Enhanced F to B is the main electrical performance advantage of the Moxon compared with a straight 2 ele beam 😊
-
cool
-
Definitely an interesting build, as for the arms could you have used Bamboo vs. the fishing poles?
-
I built a hex beam for 20m using six black widow poles. Been up a year or so with a couple of repairs. They aren't the best but they work.
-
Nice one Michael, the Moxon is up there with my favourites. I've made individual ones for 20/15/10 now. 20m is a beast. The 12m Spiderbeam pole makes a good support for all 3 and still allows you to get a height of 6m worst case on 20m. You SWR dip will change once you get it in the air but not by much as you say. The only downside is its mono band and 15 is closed so I'm building a Hexbeam too. Downside of the Hex is the front to back ratio doesn't come close to the Moxon.

I can't wait for Field Day...makes me think I might need to build something for the weekend as well. You can't be the only one with a toy to play with. Hmmm...what resources do I have out here at camp? (/me looks around and sees a bunch of sticks) Wonder if I could build some sort of a beam out of sticks for 10m.
