3 dollar antenna. Assuming you already have a 3D printer, PVC and Aluminum tubing, wire connectors, bolts and nuts, coax and appropriate connectors, etc. I was disappointed when I discovered this was basically click bait. Very cool project tho
You don't need a 3-D printer. You could go to the library and they print things for free at almost every library across america. Although I can't be a psychic and predict what happens in other countries or libraries. Maybe your library doesn't have a 3-D printer. Then maybe you can actually go to a club and find that one of your club members has a 3D printer and would probably do it for free. This video is hardly click bait
Your initial description reminds me of my own son. When he was a young teenager with his own room, his mother and I would give him our unused, usually inoperative, electronic devices such as radios, irons, toasters, and one old phonograph. He would take them apart and try to put them back together. I remember one experience when he brought an iron to me that he had put back together. He had two pieces in his hand and told me, "I think there were extra parts in this because there's no place for these." We never, *ever* plugged any of the "repaired" items into an electric socket...for obvious safety reasons! I But later, as an adult, this inquisitive kid got into computers and eventually was certified as an MCSE. He got a very high-paying job with a computer contractor responsible for national and international networks, data centres, and call centres. I guess taking an iron or two apart worked out, eh?
It's funny. I was just thinking about this today. As I tore a battery apart and took a look inside, then went to my junk drawer for something.... I thought, "hey i'm still doing it... imagine what my parents would think". Very good, and thanks for sharing :)
Sweet video. After I took my first wind-up train apart with a butter knife, Dad bought me a box of tools and let me loose on old radios, lawn mowers, piles of wood & a couple bicycles. So now I have to (a) get over Omicron BA4/5, (b) test negative for same & survive my next doctor’s appointment, (c) find a couple aluminium camp stools, some PVC tubing & a person with a 3D printner, and (d) build one of those doodads. ;-) Thanks for the grand tour. We tool users are getting more rare by the day. Stay well! 73 de W8IJN
@@HAMRADIODUDE QRZ? Yep. In there. . . . Nice simple design like that, should be easy to replicate. Without mutations, of course ;-) Stay well, amigo. Paxlovid does work but having to take it ain't no fun at all.
I nearly fell down laughing at the "SWR Oil." You just threw that in there without skipping a beat. Too dang funny. Great video. I love the re-use of everyday items as homebrew materials.
Number 1 - SWR Grease only works on 11 meters. A well known fact. Number 2 - Any antenna that shapes its radiation pattern to "steal" power from the back and focus it in front is a "beam". Whether it be a Yagi, Moxon or a log periodic. So, yer good to go. Number 3 - I think the word you were looking for to describe the holes you really wanted was "slot". By using slots you could adjust the spacing. Number 4 - There isn't a number 4. This has been great fun. Let's do it again soon.
Thank you for your explaining how to tune the moxon. I tried to make one a few years ago. I could not get the tuning right using heavy gauge galvinized steel. I did not know what I was doing. This makes it easier. The way you commented on shining the antenna reminded me of CHristmas vacation where Clark tells his son, "You want it to look good, don't ya Russ? Of course you do."
If you are noticing pattern problems, put a balun on. Such a balun can also keep electrical noise from the house from being *conducted* onto the antenna by the coax shield. Sometimes an antenna with a choke balun will be quieter than one without. The more you care about your antenna's directional pattern (long boom yagis, etc) the more you need to worry about making sure the feedline doesn't become part of the antenna and radiate in unwanted directions.
You've discovered what I've found... that a lot of tubing sizes are tailored to slip inside one another. The inner diameter of one is similar to the outer diameter of another. That's very handy.
Thanks brother, Im disabled and all my money goes to medical and this lousy cost of living. Videos like this are worth gold! And you can steal your wife's sewing cloth tape for corners, lol at your own risk. An old timer who invented the QUAGI informed me that larger diameter does have a big change on the center of the band. I shoot for 146mhz for voice. You should look up the QUAGI of the 1971 QST 73 😁
I ran your calculations for 1 inch and got 2.305 ft. or 27.713 inches. As a lightweight antenna with mine 10 gouge. I strap to bad arm and just point. Use other for radio dial and log. Estimate mine is $12.54 from Home Depot. Issue is I never got 50 ohms but about 48 as fine measure on gap never happened. But I did ISS, SO50, and now going QRP with FT 857 for dual USB/LSB sats.
Neat video. I built a 2m moxon years ago out of 1/2" copper pipe. I had issues with the spacers and should revisit it now that 3D printing is an option.
@@HAMRADIODUDE Nah, I think I'd probably draw up my own spacers. I have it mounted slightly different. Great video and motivation to homebrew antennas.
Repurposing material - excellent! Cool project and one of many cool ways I am seeing to build a Moxon. The club I am in had a DIY Antenna Day in which you could build a 2M Moxon or 49:1 Unun. Had more building the 2M Moxon and in a variety of ways including a pvc pipe frame and wood frames: some used wire others 1/8" easy form aluminum tubing (me). We used the dimensions from the same site you used and most passed muster on the analyzer. Folks had fun and left with a working 2M Moxon - some of whom used them to improve their signals on our weekly simplex net!
Great video! Once you have the material and know the correct length, things are easy. The baby steps calculating, cutting, measuring and doing it over and over again is what makes it sometimes a bit tedious.
Great video. The diameter of the tubing makes a big difference on the length of the sides. Like you said, the web sites are usually talking about wire and not tubing. I made a tape measure dipole antenna, the tape measure I used were an inch wide. Because of that my calculations for the different bands were all way to long. Figuring it all out is part of the fun building antennas. Nice video Gary KF6EWO
I was unclear in this video that the antenna builder was measuring from the center-to-center of the tubing. It appeared he was measuring from the outer edge. Additionally, the calculator(s) I used didn't give ANY variation in the specs when I changed the diameter of the wire, or designated it as tubing. In fact, most of them gave "diameter out of parameters" warnings when I set the diameter to 25.5mm or 1". I built the exact same antenna and am going to test it today. This video would definitely benefit from some actual final dimensions clearly stated or printed anywhere. By the end I was unsure what size anything actually was. But... I built it!
I appreciate you sharing the experiment and the link. I might like to make a 6m Moxon for the top of my trellis in HOA. Horizontal shouldn't be seen by neighbors.
Instead of drilling the holes, you could make a clamping mechanism with the printed parts. It won't be as solid, however it will be more adjustable. And you can retrofit it on already drilled parts!
As someone who knows Central Illinois better than most Norwegians I would say that Peoria is more pretty much in the center of the state more than almost across the state :) Anyway, great video as usual, and great to see that you not only shows what works, but also what doesn't.
@@HAMRADIODUDE That's a good haul on 2m. I'm impressed. I'm waiting on a working rotor so I can point my yagis towards northern Illinois to see if I can get W9FFF in my log on 6m and 10m. I guess 2m would be close to impossible.
Great video and given me lots of ideas, instead of using bolts to secure the plastic brackets to the metal, what about slightly changing the sloping design on the wings to straight and rounded and use heavy duty jubilee clips? Then any adjustment could be made. Good work! 73 m0kty
That makes sense! I've been having trouble focusing lately, but I will keep this in mind and it may be a good challenge for the brain. Good idea! Thanks!
Happy Holidays and thanks for the instructional video. I took your advice and hunted for a used tubular leg fishing stool, and scored one for $5. I have drilled out the rivet, but the tubes appear to be somewhat narrower in size. I have the legs separated from the seat webbing. Do you have plans or a link to how to 3-D print those support braces?
Thanks for the introduction of an antenna I’d never heard of. Pretty cool build and great instructions to go along with it. Now, can these be built for other bands?
A moxon, absolutely. You may find it to be more beneficial on bands like 10m, 20m (hf in general). There is a lot of good build videos out there. Have a good one!
hi, i think it's strange to use imperial system for measurement of antenna for 2 meters band (or other band) maybe using metric system is more coherent.
N6EF-I wouldn't have thought of using a camp chair for building a Moxon. Clever idea. I have to try that. I like the SWR oil idea. Adds some extra performance and looks good at the same time. How can you go wrong with that? Keep up the great videos.
Thank you! In fairness, the lawn chair idea was posted in many places for a Yagi (link on description), I just got lucky and found a good one at the goodwill. More to come, I believe
MacGiver (sp?) would have used a coat hanger and chewing gum. Of course, this is only necessary if you're being shot at during the build...you're probably fine doing it your own way... (On the other hand, if you try to use your new moxon while camping, you'll have no place to sit...)
@@W3OY-RAY well, depends on how many elements you have to work with and maybe conditions that day (tropo).. but o think he's actually been heard in PA. You should Totally do it
Always measure from the centre of your material to the centre of your material, never the outside or inside edges, you'll always have the wrong tune if you do it that way.
