The Moxon beam antenna is the perfect first beam for the new ham. Learn how to make a Moxon beam for your home qth, get some new ideas, and see some examples.
Thanks for the tutorial. I'm a new General-class license holder in the U.S., and I'm looking for projects to take full advantage of all the new spectrum that is open to me, without breaking the bank! This is excellent. I sure miss my days in Seoul!
Good video. Surprised hasn't had more views. Presenter has good, clear speaking voice. Subject material and graphics done very well. Rare for me to comment on TH-cam. I just may try my hand at building one for 14mhz !
Enjoyed your video. Have always considered building a moxon antenna but have never gotten around to it. Am only using wire antennas but in the past had a four element quad antenna which is really a wire antenna. Had great results with it working over 200 countries in around a two year period. No longer have it so just might give this antenna a try. Thanks again & 73.
Wow very kewl....my wife and I used to be stationed down at Osan AB and we would have to drive up to camp Red Cloud in Uijonbu from time to time....I remember having to take a road in Seoul called Unbungno...or something like that! That was back in 89-90...I didn't know anything about Ham Radio back then!! Great video...73 de KN4FTT
MOXON is great small space antenna. vertically mounting seems like work well. they also mtches to 50 ohm just fine, if it choose right dimension. I use 4NEC2 simulator to determine best dimension for use. AG6JU
I built one for 11 meter a few years ago out of copper pipe and spin it with a TV rotator. Up about 40 feet. It works a treat. Talked to every continent,except Antarctica, from Canada. My next upgrade is to add a director to narrow the beam down and add side rejection. Excellent video. Thanks
Great video. I will have to look into this myself although I am not very "handy" when it comes to building things I have never been successful so far in my endeavors, lol. By the way, Thanks for the THOR QSO last night.
I had fun! Too bad condx aren't great. I'll get up and running with FT8Call after it hits mainstream. I now have a basic 2el yagi of wire/pvc/fiberglass. It's got a boom about 1/3 as long as the Moxon. The Moxon is the better overall antenna, but the 2el is lighter. I was worried about the moxon's heavy PVC boom I was using, and the high winds we had in Spring. Had it up 1 1/2 years, though. I miss how 17m worked off of it without much loss, as well.
Unfortunately, I live in a Home Owner's Association which it seems has an unrealistic fear of antennas of any sort. I had to fight them tooth and nail and have my attorneys threaten legal action against them for violation of my First Amendment Right to free speech and denying my right to exercise a federally issued license to operate a radio station from my home address which was listed on the FCC license before they finally backed down and approved the antennas that I currently have. I am not even able to temporarily set up an antenna to see if it will work in a particular location or not without first having to fight with them and trying to convince them of the dire need for another antenna, then submitting detailed schematic diagrams of the antenna, exactly how the coax will be routed and enter into the home, and exactly how and where it will be installed along with a minimum of 3 photos of the exact area showing various views of the installation location. When I submitted the application for my antennas I was not using the G5RV Jr antenna so it was not in the approved permit. I am basically hiding it behind my house hoping they do not look very closely. Since the permit approval, my vertical which was approved is no longer functioning well so I am using the G5RV Jr as my main HF antenna for both NVIS and DX. I am hoping that since my antennas have now been up for several months through the fight over them with the HOA and there not being any complaints from my neighbors of electronic interference or "glowing children" from the dreaded radiation given off by the antennas that they will loosen their death grip on me and it will become easier to experiment with various antennas. Hopefully, by then, I will have been able to successfully build a Moxon antenna so that I can try it out. One of the things I also worry about here is wind as we generally have around 20 MPH winds every day, and gusts much higher during storms. I lost a flagpole last year in a 79 MPH gust when the 2" aluminum pipe broke in half at the concrete base. Ahhhh, fun times, lol.
That's a shame about the typhoon. If you built one for 10m maybe we could make contact on 11m when the conditions are there. I'm in central Victoria, Australia. We do get propagation from your part of the world. I have had some great successes with Moxons, and this latest version has proved very good for local beam to beam. I think they are a special antenna with a useful take off angle.
Great Video! I build a moxon for 27mhz with 1,5mm wire and fishing rod. The total weight is 2,2lb (1Kg), so its perfect for field days or SOTA activation. Could make contact with more than 7000 miles and this of the cycle minimum. 73s
Very good presentation with some helpful information. I'm currently trying to scale a Moxon for 27Mhz, I think it's the wire insulation detuning it too low (used moxgen). This one is a fibreglass type, we have built aluminium one's too as you easily can on the higher frequencies. Do you ever get on the CB band, say 27.355 or .385?
I took it down, due to a typhoon. Will go back to a moxon, possibly next year. It worked well on 17m, but acts more like an out-of-tune dipole as you get further from 20m.
MOXON cover wide range entire CB freq range should be covered . off frequency less F/B ratio, but about same gain. I use 4NEC2 for simulation, it works very well. AG6JU
Really well explained with just the right amount of humour! I'm inspired! I may well have a go at this. Question: if using a centre support pole, can it be metallic or is electrically inert best?
It can be metallic, but you need to keep the elements isolated from the boom, to stay with the Moxon design as intended and remain a 50 ohm antenna without need for a match.
@@thestingyham1188 Thanks for the reply. After watching your excellent video, I did some further reading which concurs with what you say in your reply. Thanks again. Best 73.
I don't believe I altered the gap size at all, and it still worked, accounting for wire velocity factor. Not at this frequency, anyway. Something larger like 40m might be different, and take some experimentation.
After calculating, the gal difference is less than 1/2 cm between a frequency of 14.200 and 14.555, when adjusting frequency to account for velocity factor.
No, I haven't, because I read that 17m and 20m may be too close to one another. I find the 20m moxon is so wide-banded that it works really well with maybe only 15% additional loss due to SWR, if I just tune it to 17m. I did add a 15m to it, temporarily, and that worked.
@@Swampfox10mm yeah... I read the same about 20 and 17 elements too close to each other. But there are people that built it and they say that works fine... That's why I'm curious about it. Maybe I'll try to add 20 meter elements to my 17 meter Moxon and see what happens.
For those interested in building a multiband Moxon. I built a 20/17/10 meter Moxon using individual feed lines and 1:1 baluns for each band. All three bands show directivity as expected, good swr and not interaction between bands. Very pleased with its performance.

Bummer that the Moxon Project website is gone. Fortunately there are still some moxon calculators online.
I’d like to build a 10m moxon for my attic.

Moxon VS magnetic loop?
Quick question, if you alter all the lengths to take into account the velocity factor of insulated wire, shouldn't the gaps stay the same?
I don't believe I altered the gap size at all, and it still worked, accounting for wire velocity factor. Not at this frequency, anyway. Something larger like 40m might be different, and take some experimentation.
After calculating, the gal difference is less than 1/2 cm between a frequency of 14.200 and 14.555, when adjusting frequency to account for velocity factor.
Checkout some AM radio vids by Gary Debock. Like when was the last time you heard some stateside AM DX?
Dubya P yes Gary Debock and don’t forget Guy Atkins
The Moxon looks to be a derivative of Fred Caton VK2ABQ's design from back in the day .
Have you tried building a dual band 20/17 meter moxon?
No, I haven't, because I read that 17m and 20m may be too close to one another. I find the 20m moxon is so wide-banded that it works really well with maybe only 15% additional loss due to SWR, if I just tune it to 17m. I did add a 15m to it, temporarily, and that worked.
