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 📻

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 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

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.

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

Either keep those wooden booms dry, or seal them well. Also, if you've carefully gotten anon-conductive mast for that vertical polarization installation, and you run the COAX down that mast from where it attaches to the boom, the outside of the shield is a conductor being put right back where you don't want it. Much better to run the COAX off the back end of the boom to keep it beyond the reflector. Keeping it from dancing in the wind is a separate problem. Though when hand holding it from the back, having the COAX comer out thee back is what you'll want anyway.

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.

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.

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.

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.

@@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
