I had the opportunity to find some old Camping stools from SAVERS, a local thrift store, so I destroyed them and made a Moxon antenna!
I have heard the stories of a Lawn chair dipole and Yagi - (Check out • The Lawn Chair Dipole ... for Ham Radio Crash Course's Lawn Chair Dipole) or qsysociety.org... for a 6 meter lawn chair moxon (This idea is nothing new)
Links referenced:
Antenna Top Moxon build instructions (VERY GOOD INSTRUCTIONS) - These instructions are super easy to understand and the detail that is gone into is not overly complicated : www.antentop.or...
Moxon calculator in multiple measurements (Inches, Feet, MM, etc) - tippete.net/cgi...
I forgot to mention why this Moxon really wasn't $3.00:
the metals were $3.00, but nuts and bolts cost me 11.50 cents. I used stainless steel nuts and bolts.
The coax was RG59 which was laying around. The PVC I also had laying around. I would still say this could be built for less than 20.
I will have the spacers available on Thingiverse in the future.
In FULL clarity: My motivation from that spacer came from my Hygain 5 element Yagi, which uses a cool, similar piece. I have a few ideas for the future improvement.
I realize this is a long video, but I wanted to document how i went through this build, in order to help others. I openly admit that I am in pursuit of knowledge every day and I am just as wet behind the ears as most, but I ENJOY this kind of learning and I know others do as well.
Thank You for watching.

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

@HAMRADIODUDE 4 месяца назад

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?

@HAMRADIODUDE Год назад

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 :)

@haramanggapuja 2 года назад

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

@hammathguy3995 2 года назад

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.

@thunderjagman 2 года назад

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."

@HAMRADIODUDE 2 года назад

You are welcome!

@JeffSmythe-f7e Год назад

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.

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 😁

@garyclark4930 Год назад

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

@jonathanhaynes9950 Год назад

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!

@labcat73 Год назад

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.

@howardkarse9915 2 года назад

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!

@HAMRADIODUDE 2 года назад

Awesome! I am glad to hear others are enjoying the homebrew stuff and finding useful uses for stuff that may not longer be useful! Thanks!

@loclhst 2 года назад

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!

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.
