- In this video I show a article from QST magazine that is from April 1993 on how to build a 2 meter Yagi for 7 bucks. With inflation you might actually be able to build it for the price of a Fast Food Meal Lol.

I built mine from a 1 inch square aluminum tube and aluminum rods, from a local hardware.
I'm 73 years old not in the best of health, so I mounted it as high as I could reach on 10 feet of pipe, @ 6 feet.
I was using my icom 208H, but since it broke I have been using my Yaesu HT to check into the ARES net repeater about 17 miles away and another in the next county about 20 miles away, I'm happy with it. Thanks for showing how easy it is to build your own, that after all is the art of radio.🖐🏻73's🎙🎧 KD9OAM 📻
You're welcome, just trying to pass on good info for everyone! Thanks for watching and the great comment!
17 miles with an HT? Very impressive!
@@ScottPlude Thank you.
I built that antenna back then and then made it into a 7 element and it worked for many years. I still have it but it's not in use anymore. Definitely worth building
I made mine into a 4 element and it just works!
Cool build Chuck. It's amazing what stuff lying around the house will work for an antenna. Even the few parts you have to buy for this - still super cheap.
I actually am thinking about getting a 2M Yagi to point out of the 1 window in my apt that doesn't look out on a building. Might give this a try.
Good stuff. I just made a tape measure yagi. While it works great, this design is a lot cleaner and I really like the way it can be broken down to store in a single tube. Thanks for sharing an old article with a new ham.
Thanks for the links, Chuck! I'll be building the arrow antenna.
Nicely done. Getting the elements all in a row on the PVC is not always easy. You really did a nice clean job.

built one many years ago... went and find it on the antenna pile, metric sizes. refl 1016 mm, driven ele 507mm each side, dir= 886 mm spacing 440 mm and 440 mm yes both the same spacing, works like a charm , draws repeater 140km away with 1 watt.
boom 25.4mm plastic pipe, elements wrapped at boom with thin copper wire to prevent element movement.
cheers zs2cx
Mine was only a 4 element because I wanted to see if I could make it portable. My elements fold so I can, the other eliments will be used for 70cm. Lay it out to see how many elements are useable. Other than that as you pointed out, the isolators are the only real consideration. GL with your build
Nice build Chuck, I did something simular out of an old tv antenna and it works great. I use it in the backyard on the weekends while I have my coffee and chase SOTA.
One note on that PVC tee you cut, it works great but I found that a simple ty-rap really helps while rotating and if there is any wind.
Keep up the great work/content. 73
That's a good Idea especially in the wind.
Don't need to be a new ham to enjoy good content. Thank you sir!
Great build Chuck! Nice work mate
Thanks Hayden!
A little pro tip, if you ever want a perfect straight line on a round pipe, just lay it in a piece of angle iron. Also 2 pieces of angle iron and a couple of c-clamps work well to hold pipe steady while you are drilling.
Great video !! Thank You !!
nice video! thx for making it
I love this antenna, built one a few years back for fox hunting, It really does the job. Thanks for the videos! I really appreciate your time and effort. 73 de KM4KAQ
Eric, it really does work very well. I made a contact on 2m SSB about 100 miles checking into the Bozo net, but the net control has really good antennas and I was at a good location. Thanks for the comment!
Always doing some cool stuff. Thanks for sharing your knowledge. KO4HPC 73
Take a strip of paper and wrap it around the pvc. Tape it to itself then slide it off the pipe. Flatten out the paper ring you just made and mark each end. Put the ring back on the pvc. The marks should be exactly halfway on either side.
Just built mine and ironically the pvc parts cost $7. (the rest I had in my junk box).
That's cool, Chuck... Now, nothing against the tape measure yagi but I like your design much better. Looks professional. If I'm hunting rfi in my neighborhood my neighbors wouldn't think Im completely nuts with this..
You can cut 40 inches from a roll of Aluminum clothesline cable for the reflector
Making a UHF handheld Yagi for my HT. I'm considering using 300 Ohm twin lead so that the tuning will not be dependent on the connection point. Gamma tuners are PITA to make and change. The Delta has worked for me, but I'm curious if twin lead will fix this. Then I'll have to make a small toroid 4:1 transformer to connect to a short piece of coax to the HT.
I enjoyed the video about the two meter yagi . What I would love to see you do is a video how to make the hex beam antennas for six meters. That would be a huge help for me and others . Thanks 73 AE4OY William Peacock EM-81UF SOUTH EAST GEORGIA USA
I'm an older Ham, and not as portable as I used to be. But I have made 2 and 6 meter beams before and I have the carcasses left over from two hurricanes that destroyed both beams so I have the booms left over from both. 6 meter beam will be three elements, but I want the 2 m beam to be seven elements for additional gain. I will figure Dbd gain instead of Dbi gain as Dbd gain is more accurate. Your construction looks good to me! I advise others to have no fears constructing this project, just go for it! 73's de W4FJF.
I did add a 4th to mine with the same spacing, thanks for watching!
hi from Poland , this is Jack SP6KE , I hope you well . I both a cheapest dosen arrow shafts (30inch) for a 25 euro and I trying to make VHF and UHF yagi ... for a satellites
Hi Chuck! Thanks for the video! May you tell me the size and threaded of the arrows/nylon rod? And what size is the reflector and director aluminum rod? Thanks in advance!
8-32 is the thread size and 2.5-3" depending on your boom, I think the rods are 1/8" even a wire coat hanger will work lol, thanks for watching!
I find making my own antennas are far better than store-bought.
Always good stuff. Good antenna build ideas. Thanks. KJ6DQ
Chuck what was easier you
5 element or this one.
Thanks for sharing

Did i miss something, or did you explain what materials (rods/tubes) for the pvc version?
Tape measure elements
Would copper founding wire work?
Neat project! I'm going to give something like this a shot.
I think your third "Threaded Rod" link in the description might be truncated (it doesn't work and appears to be missing a couple characters at the end, perhaps).
Also doesn't tell us which one to order. 8-32? 10-24?
are your measurements of the elements center to center or the distance between the elements?
center to center
I wish it were easy to make one for 10 meters
You and me both lol , thanks for watching
@KK6USY Ham Radio Adventures I found a video with 2 wires 8.5 ft each and a balun so trying that tonight.
Workin on a technical license, have a question why can you build
A horizontal and vertical plane and use a duplex like a 70cm/2m
Thanks
Bob , I don't understand your question, I think if you look at arrow antennas that might answer this for you. arrowantennas.com/arrowii/146-437.html or Elk antennas, elkantennas.com/product/dual-band-2m440l5-log-periodic-antenna/
@@KK6USYHamRadioAdventures
Sorry for the confusion, i see that people rotate thier Yagie from the horizontal plane to the vertical.
Just curious why no one has made one with elements for both plains for one freg. So you dont need to rotate it from horz to vert for diffrent stations.
Im sure there is a reason because there are people WAY smarter than me 😉
Thanks Bob
@@bobdefield7842 Oh got ya yea they do make them that way I did a video on one 1 elements, but Mike the owner of M2 antennas says to set at a 45 degree angle and it will do pretty good with just a little loss each way

KK6USY R O C K S . . . 🎸💯
Good video but definitely not a follow along or step by step type instruction missing measurements
He's an easy read. Needs a new wife.
Too many commercials
Kd2yww love the videos
