    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 📻

    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

    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.

    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.

    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.

    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.

    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

  • @KeepEvery1Guessing

    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.

    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.

      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!

    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.

    What kind of SWR are people getting with this antenna? I've built it two different ways and the SWR has been awful (the first attempt was adjustable like the original build in the article and I think I barely got it under 3:1 at best. Making it a fixed length like the video suggests leaves me over 5:1 and confused as to how to even try and fix my second build and I used much more expensive materials this time because all the links to the materials in the video are dead.

      @@KK6USYHamRadioAdventures I can try to rig something to get it in the air (before I give up on this completely and buy a pre made one for barely more than I've got in this project now 😂) but it didn't seem that relevant to me. The SWR is awful, 3 or 4:1 at the top and bottom of the band and a bell curve up to nearly 8:1 right in the middle of the band. I built it of 2x2 and copper pipe so it's kinda heavy and would require some thought and effort to elevate it correctly.

    • @jopshua4703
      @jopshua4703 2 месяца назад

      D'oh, I tried a different handheld as the power source and it was around 2-2.5 across the band. Think my other HT may be kaput. Still would love to get it closer to your numbers but I can work with this I believe.

      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 😉

    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.
