Just built this antenna and put it on the air. First contact was New Zealand, 8449 miles. Easy to build, and works great!! Thanks for sharing this plan Toivo
Many thanks for this very clear explanation. Will try with drive away markers but the longest I found in Amazon are 72” and would need about 75” to accommodate your measurements. Guess will have to increase the boom length a bit and do some eznec simulations
My recommendation would be to just extend the driveway markers out by using a 1 by 2. In other words, mound the markers out from the center of the boom to get to the right dimension. I just did that recently and I used cable clamps to hold the markers onto the 1 by 2. Thank you for the positive words!
For two and a half years I have used a fixed Moxon at 68 deg 20 feet off the ground for 20 meters. I have worked from New Zealand and Australia to Greenland and Finland, Indonesia, China, Japan, East and West Russia, Europe, Africa, North and South America and all 50 states. I am convinced that the Moxon Antenna is the best simple wire antenna available for hams. You have inspired me to remake it so I can rotate it. In all I have confirmed 76 countries, 6 cotenants, all 50states and 730 US counties. Thank you from KF7BWS.
Im not a ham but i use a moxon on 11m cb. I contacted vietnam china and the guam 27.385 lsb the first week setting it up 20 feet high in my 2nd floor apartment. Amazing antenna
Grate video I look forward to more from your new channel you did a grate job antennas are one of people's main obsessions in radio me included I look forward to more
Very cool. I love to see this. Nothing wrong with buying station equipment, but building what you need from materials you have on hand is what it's all about. Thank you for sharing sir.
You can make the dividers with nylon thread. They can be used as two round electrical terminals. It will be much lighter and will give a better adjustment of the ROE.
I am sorry but I have no clue how the building goes when it comes to the fishing rods . Is there a specific shape/angle that we have to bend the rods in to ?
The shape is not very critical. Make the wire harness and attach the wires to the poles or rods you are using with black electrical tap. Tie wrap or tape securely at the point where they leave the rod and head for the insulator strip. Once it is all secured, it will have its own shape. I have built them with various fishing rods now that bend differently and they all perform the same. Have fun and don't fret the angle too much!
Can you please do another video and show how you interlaced the 10 and 15 meter moxons when you did attempt to have then interlaced. I have found very little literature and or videos on how to do this. Thank you in advance!
I never did try to connect them together and only used separate coax runs. If I were to do it, I would likely try bare copper wires with about 1 inch spacing between the feed points and them attempt to connect the coax somewhere along that copper wire interconnection. Not willing to spend the time on it myself so give it a try and report back on your results.
@@dmoney4622 The antennas in those graphs had their own separate feedlines. That graph shows how the antenna's physical interlacing affected the SWR. A bit surprising in the direction it took the responses. Good questions!
The Black Widow today is carbon fibre, was this not an issue if yours were, as carbon fibre absorbs RF? You also mentioned glass fibre so maybe yours were made of that?
All the Black Widow rods I have seen are fiberglass. If I see any carbon fibers ones, I might order a set to evaluate. Just checked Cabelas and they are still fiberglass.
@@W8TJM Too large on 10m band? should be more or less the same size (had them both on the same pole, not at the same time that is, lol) but then again, what do an old radio ham like me know, lol Anyways, the delta loop was fed as a vertical and most times did much better than the Moxon without the need for rotator. Enjoy Ham radio testing is all part of the fun.
Thanks for the compliment Jason! I bought the RCA VH226E rotator two years ago and have been impressed with how well it works. It is around 120 dollars at Amazon and 109 dollars in other places. I have given it a lot of use and no issues. The push button direction setting is very convenient. For light antennas mounted close to the rotator, it should last quite a few years.
@@W8TJM Thanks for the quick response. The price on the VH226E isn't bad at all, especially considering how expensive some of the HAM-specific units are. I think I'll pick one up when I try a Moxon build this spring. Cheers and 73. Jason W2ASH
Hi Toivo. I think your design is very clever. Re the interlacing affecting 10m VSWR, given you have seperate coax feeds, why not lift the 10m antenna higher on the mast to get some vertical seperation to the 15m antenna. I’ll bet as you lift it there will be a point where the VSWR starts to return to levels like the independent readings you got. Worth a try? Cheers Trevor VK3DCQ
Trevor... That is a solid suggestion! I think it would indeed get the antennas to be a bit more independent. Only negative is that it adds weight with the additional boom and bits needed, but it is certainly worth a go.
Analyzed them (21 segment arc approximation) before building them and the performance is very close to a normal rectangular version with some parameters life forward gain actually better. Turns out the length of the elements is more important than the shape.
Hi Toivo Excellent antenna build!...I am currently using a single element 10m elongated rectangle loop and it works great...have been thinking of converting it to a moxon using the same footprint..your video is motivating me to do that👍 73 Steve W8SAW White Lake
Those lengths are in the video under the wire assembly instructions in meters. In inches, the reflector is 194 inches long and the director halves are 91.3 inches long. I hate doing English conversions so always use metric. 73

At 5:55 you said you interlaced the antenna's and showed 4 swr graphs ... Doesn't that mean they only had one feedline?

Also.... Check out the QRZ page for HB9DSP and you can see one implementation of a multi-band Moxon. He has had good success with it.

@@W8TJM I've ordered a different set of fibreglass ones, so will be building soon. Thanks for the response.
Do you think there would be an advantage to angle the driven element up to increase the takeoff angle?
It seems keeping it horizontal works the best. You might try modeling it with EZ Net to see what you find. Usually you want a low take-off angle.
After years of trying out simple antennas the one element delta loop topped them all, not to mention the big decrease in QRM.
I am a big fan of delta loops also, but they end up being a bit too large for the area where I live. Had one back in 2015 and it did indeed work well.

If you ever decide to sell the 10m version, please let me know. Unfortunately, I can't build antennas myself.
I did sell two of them locally. If you can find someone still stocking the MFJ Moxon, that is a pretty good deal at 160 USD.
@@W8TJM I'm very interested in your design. If you have one available for me next time, please let me know. I'm not in a hurry.
Has anybody eznec these different arrangements?? I am curious to see how the results differ from actual measurements.

Sure. Just make the wires a few percent longer.
