Awesome, can't wait to build one soon!! I enjoy watching your videos
Interesting, good planning and the older Icon and Military low band radio was a treat to see. Thank you for sharing your expertise! I will have to try a Moxon for 'Fox Hunting", thanks again
Very nice antenna, with an interesting explanation. Tks fer sharing your knowledge. For eleven meters band I home brew several antennas. Gain master, End feed with an old tv components, Delta loop and 🧲 loop my last. And now I'm surely motivated by you to make this project for 11 meters. Tks 7351.
That's a great presentation , I have had several ask me to build one but I had decided to go quad antennas instead . This design has some interesting things on its side the fact that it's only 2 dimensional is a plus when transporting . I bet it could talk 280 miles on 2 meters with groundwave . We all know when conditions are in you don't need a large array so a great test is ground wave , that is if you can find someone to talk to. I was lucky we had a family vacation at Crystal Beach , Port Bolivar ,Texas USA close to Galveston . I used a 4 and a 5 element at different times to talk back to San Antonio and Banders Texas longest was 280 miles down to 220 with 6 members of our Hamster radio club. My elevation was 15' off sea level with 50 watts USB then on that 10 watts . So your moxon should do good and the pattern would easily cover a large City from a 100 miles away. Keep up the good work.👍
Thanks, indeed. Another advantage is that the beam isn't as tight as my 6el. Yagi-Uda...
wow long time between part 1 and 2 LOL :) luv your vids Gil keep up the good work.
Thanks, better late than never ;-)
Merci Gil. Tres bien Mon ami.
good demonstration, narration.
Thank you!
Always good to build and test Gil! I too build and test different antennas and always hopeful for any 6m activity! All the best! Bon- KX4EZ
Thanks. Definitely, and I will use them again..
Good stuff Gil and I know you had success later on. I've been reading up an it seems possible to make a multi band version for say 2, 4 and 6m. That would be good for prepping.
a brilliant video, very very informative and very usefull. good to see my partreon money going on new stuff and ideas, keep up the great work
Thank you, much appreciated!
Hi Gill great effort especially with the cold winter wx on the way👍👍 4C here in Liverpool this morning but I am sitting by the fire in door's hi hi.. If it's any consolation I still have never had a contact on 6Mtrs SSB but mainly due to not having an Antenna up for that band yet. Keep up the good work.
Will do thanks! And I will keep calling on 6m sporadically...
I really enjoy your enthusiasm Gil 👍👍👍

Thanks Julian :-)
we appreciate Julians and Gils vids. Thank you both for sharing your information with the rest of us.
I am currently making one for 11m CB DXout of an old mains extension cable..haha 73 from vk4
Great video mate cheers.
Thanks!
Thanks for the videos I am building a portable wire moxon using pvc
Post photos on radiopreppers.com!
Great videos, great explanations, and plus, very nice and clear English pronounce, really easy to understand, also for an Italian guy :D Thank you very much and 73 de IU1MRY
Thanks!
Thank you so much Best 73s please do more vedios
Will do thanks.
merci pour ce partage , superbe antenne . 73 Gil
Merci.
Lol had to laugh because of the hampster on your mic. Great video, lol, still laughing. I'm gonna build me a 2 meter moxon soon. Yep still laughing, lol just subscribed lol
Welcome aboard :-)
Keep up the great videos , they're always excellent ! The one question I have, is your microphone related to beaker the muppet ? 😉
I'll have to Google that one up! LOL.
I have used yagi's and quad's for communications above 30 MHz. Then I read an article in one of the US amateur radio magazines about a ham that combined the quad and yagi that he called the quagi. I tried that concept and it worked great. My most difficult part of the build was locating a length of cedar to use as the boom. I am going to try the same concept using the moxon 2 element beam and some yagi elements for directors to determine if the directors will help with distance. Thanks for the 2 videos on your build. KB8AMZ
Interesting. I think I have seen one somewhere on the web... It should definitely help.
Nice build. I’m looking at making a UHF moxon. For vertical/Omni-directional operation, how should I position it?
See part 1, I made a UHF Moxon then. Vertically for FM, horizontally for USB.
Sure I saw something moving in that microphone pop cover.
Have a listen next Tuesday night. UKAC contest on 2m ssb. I should be out /P on 10w although I doubt you will hear me unless aircraft scatter helps out. I'm normally in IO93JJ.
Thanks, but contests are not for me... At all... :-)
Hi Gil will the MOXON antenna work for contesting on 2 & 6M bands I was thinking of building a Delta loop antenna for them but like the look of the Moxan antenna
I don't see why not. It throws a slightly wider net than a Yagi. 5db ought to help..
I seem to be mentally tuned in lately to videos -- both old and new -- with somewhat positive reviews of equipment not working. Particularly from a prepper or homebrew perspective, I appreciate that you are doing the work to build and experiment so I can learn from your experience. In a case like this, though, can you say there is any information to suggest that the effort is worthwhile?
Which positive review of something not working?
@@RadioPrepper In this case, it was a 6m moxon antenna: fun to build, inexpensive, lightweight, low SWR, ability to receive (found a beacon), but no demonstrated contact. Very anti-climatic ;-) // I am enjoying your videos very much, though--including your latest regarding your sailing incident. The honesty there and in the ham radio field operations (sometimes no qsos) is very refreshing. For a build though, we have to know if it works :-) Merci, Gil & 73 de ab3ww
Any thoughts, on the vertical rather than horizontal mounting for this particular antenna???
Vertical for FM, horizontal for SSB. Par convention..
3:00 Gauge 14 (up to the right) whats kind of misure is it?
How high can you go on the 12m spiderbeam pole with LMR 400? I saw dj0ip's site claiming that LMR400 is too heavy and recommending LMR 240. But I assume you could run LMR400 up to ~9m if you remove the top sections of the pole?
Exactly. I tried up to 9m for my 2m halo, did not try higher... The antennas is 1Lb.
Nice Antennas!
128, Jan
Thanks.
Hi Gil, do you think there is a chance you could get a LOS towards Paris ? If yes, we could try and arrange a 2m SSB QSO...
I have a tape-measure 3 elements yagi and a DIY GP for 2 meters, so not the best guarantee that it will work, but you never know until you try :)
There are some high grounds nearby (saint-cloud, mont valérien), from where I could operate. This would help on this side...
LOS is impossible. Tropospheric ducting maybe but the chances are slim and unpredictable.
you may like too try a hb9cv for 2 meters it is quite small with good gain.
I'll check it out thanks.
Hi Gil,
greeting from the UK.
Very interesting design. I am searching for an antenna design to work on 2m FM. My goal Is to hit a repeater in the north of France 200Km from south coast of England using a low power portable (max 5w).
Do you think this design could wrk wit the right conditions?
Possible, but the major factor is height...
@@RadioPrepper Got it Thanks.
Hello Gil. I learned something new today. Thanks. Always great to watch your videos. Why not contact Calum the DX Commander in the UK and arrange a time to check it on 6m. Would be interested on how this would turn out. Hope all is well. John N6NRO
Great thanks. I have corresponded with Calum before... It might be a bit far for 6m. If there is an opening maybe...
Great video! How about making one for 10 or 11 meters? Sounds like it would be an awesome project!! ;)
Good idea thanks. The size would still be reasonable.
@@RadioPrepper Yes! And I think it might be easier to get contacts!! (especially on 11 meters) ;)
I would make one for CB, never use 10m..
Looks like your shorter one was horizontally polarized and the bigger one was vertical. Right? Can you discuss more?
Correct. The 2m model I use USB with, so horizontal polarisation. The 6m model is for FM, so vertical. If I used USB on 6m I would go horizontal.
Can the moxon be used in vertical polarization?
Absolutely yes.
Yes the moon is a great antenna. I think you will find that the swr and tuning generally is very dependent on capacitance and leakage between the opposing ends. Having wood there is most definitely a no no. David G0UPK
Many thanks for this video, the antenna sounds very interesting. I wonder, as for 145 MHz the antenna is small (about 80cm x 30 cm ?) , if building it with copper tube, could be interesting allowing more rigour (sorry for my english, I mean "rigidité) and so less reinforced with only one large piece of wood or PVC tube, perhaps too a larger bandwidth if the tube has a diameter of 1 cm ? I have too some hesitation for another antenna, a biquad with a reflector (if this reflector is meshed, the classic lamda/20 gives a size of the cracks of less than 10 cm, let assuming 2 cm, would give a light reflector even with wind), the gain is given for 7-9 dBd (according to the distance adjusted for an impedance near 50 ohms). What do you think about using tube for the Moxon antenna ? Have you studied this biquad antenna too ?
Many thinks again, sincerly yours, Milos
Thanks Milos. I did use 1cm tubing. It could probably be made lighter and more rigid with bigger diameter thinner tube walls, maybe aluminum.. I might make a biquad in the future!
@@RadioPrepper You certainly did a good choice with a 1 cm tube, sorry as I miss it. If you make a biquad I will wait with a lot of impatience.
Sincerly yours, Milos
Thank you. Maybe for UHF...
Speaking of small(er) antennas, Gil have you or anyone tried the MFJ mini dipoles. e.g. MFJ-2240 in particular
-Don wa8qzz
Not me.... Anyone?
Could you tell me what mast you use?
Spiderbeam 12m mast.
Et les vidéo en Français s'est bien aussi
Metric IS standard, imperial is the exception mate!
73s de a71br 👍👍👍👍
FB Gil! Agree. A Moxon is a great alternative to a full-size Yagi when you need a bit of directionality and gain. I put up a quick 20M vertical wire Moxon for skedding with our common friend Ray. It was only about 1.5 meters off the ground but worked nicely. I tried both center-fed and end-fed. Both worked equally well. VY 73 DE N6MGN
Excellent Paul. I should try to contact Ray from here again, and you maybe.
Metric IS THE STANDARD !!
Metric is so much easier...
2m SSB is really dead most of the time. At least during the week. A little more traffic on the weekends. When I was a young radio amateur 35 years ago I used to walk arround with an IC-202E and a HB9CV antenna. At that time there where always some stations ready for a chat :-) Every now an then I use my FT-817 and the same old HB8CV, but most of the time there is only white noise on 2m SSB :-(
Nevertheless great video again! 73s Stephan, DF6PA
Thanks. Let's bring 2m USB back!
@@RadioPrepper at least once a year we have a so called Rheinland-Pfalz (Rhineland-Paladia??) activity evening for two hours. Its some kind of local competition and always fun: photos.app.goo.gl/GgJbJkYFoCkVejcW8
You don't have any gain AND you don't have any nulls. Nulls are handy for removing QRN/QRM.
Best 73s de a71br
Thanks!
You might try calling again with your 2m horizontally polarized. Most people on 2m sideband are using horizontally polarized antennas, so if you're vertically polarized, you get a significant loss when working someone that is using horizontal polarization. 73
Definitely. I was horizontally polarized.
@@RadioPrepper sorry, it looked like you hung it vertically. I might have gotten confused on which one you had hanging that way. Or maybe I'm confused on which way is vertical vs horizontal with a moxon. Sorry for my confusion, was just trying to help :)
Rewatched. I was confused as to which one you had up that was hanging vertically. The 2m at the end was up on top horizontally. The 6m looked like it was hanging vertically in the previous shots. I got confused as to which was which. Posting this for anyone else following this conversation. 73 again
No worries. My 2m Moxon was horizontally polarized. The 6m one was vertical.
Sorry. But the mic looks like a beard simulator to me ;). But: Video's top!
Thanks.

At the very least start off by telling viewers that THEY NEED A LICENCE to operate on the 2m Band, the 4m band and 6m band along with every other freq allocated to amateurs. SSB signal is 2.6 KHz wide, FM CHANNEL spacings - Narrow band FM is 12.5 KHz at 2m, Wide band FM is 25 KHz at 70cm! Unless you want to run 'digital' in which case the channel spacings are 6.25 KHz regardless of mode or frequency!
What is the deal with the strange Mike that he is using. Is he trying to hide? Not real impressed.
The hairy thing on the microphone is designed to cut wind noise, thus obtaining the best audio possible outside.
