    Mike I read all the comments and it was asked before. Can you please let us know what the final length you cut the antenna at? I have mine together but having a hard time with the tune. TIA

    Thanks Mike.. I typically don’t purchase wire antennas, but this one looks simple enough for me to assemble and use resonant ready.. it’s high in the consideration list. thx for sharing.

    Good work Mike. I home brew 3 so far and they all have a slightly different VSWR curve but my FT 817 is very happy on the VSWR meter with all 3 antennas. My regular SOTA antenna is the 3x18 for 21 total turns but it needed the 10 turn coil out from the feed point end to tune up best. Great antenna. Regards vk5cz ..

    I was using speaker wire vertical, my recieve signal was a solid 6, on a station from Italy 🇮🇹. I changed the speaker wire to 6mm Earthbond electrical wire, the signal jumped to 9 + +

    Mike, nice report. Thx. What length wire did you finally settle on? I built the EFRW 9:1 version last week. 29’ of AWG 26 hi viz. works great! I used 2mm banana plug to connect the radiating element. I’ve got another one of his kits here and will be building the EFHW Version this week.

  • @johnwest7993
    @johnwest7993 4 หลายเดือนก่อน

    Drill out the hole for the 9 to 1 if that's the impedance ratio you want. Then add a switch for either 9 to 1 or 49 to 1. That's what hams do. They make things work the way they want them to work. BTW, I prefer tapping to twisting, because I think tapping is a percent or so more efficient, but twisting is more mechanically reliable.

  • @robertmeyer4744
    @robertmeyer4744 11 หลายเดือนก่อน

    great antenna build. looks like a easy kit. for that ferrite core the twist is not needed or is the cross over half way threw the winding. all that cross over i for is so antenna lead is opposite the coax input. that uses a PCB . if makings that a 9:1 you may need counterpoise but depends on length of feed line. and choke at radio . if using counterpoise choke at antenna . I haven't needed a counterpoise with 25 ft or more feedline. 73's

    After watching this video, I checked out my parts kit and found a T50-43, 100pf cap, and I had a BNC. So I made it myself but, have not had much success with the EFHW tuning. I also found that my soldering skills are not what the used to be as my eyesight isn't what it once was. Too much solder, and created shorts. Some kits are pre assembled which are tempting to purchase. However, after all of this is said and done... I'd still prefer to make my own and gain the confidence & joy of building it myself. 73's de kd5smf

    • @hamradiotube
      @hamradiotube  9 หลายเดือนก่อน +1

      Heck yeah man thanks for commenting! I do spend a lot of time tuning them. Most of which is edited out. I put it up, take a reading, bring it down, cut it, put it back up, take a reading, etc. etc. etc. It takes a bit of time to do that. Maybe an hour of solid tuning to get it perfect, but once you got it, you got it. Totally worth it. And I never have to take a tuner with me.

  • @denniskwasnycia1950
    @denniskwasnycia1950 10 หลายเดือนก่อน +1

    Noob here and hope my question is not too laughable. Will this antenna work for GMRS and CB as well?

    • @hamradiotube
      @hamradiotube  10 หลายเดือนก่อน +1

      You could tune it for the CB band, sure. That's only slightly lower than the 10 meter ham band. GMRS, not so much.

  • @Rabbitears1
    @Rabbitears1 11 หลายเดือนก่อน

    Mike,
    Do you normally run 50ft of coax for your EFHW and also, do you usually run a choke
    at the transceiver end? Thank you for what you do my friend!

    • @hamradiotube
      @hamradiotube  11 หลายเดือนก่อน

      Sometimes I do, sometimes I don't. Like much of the answers in the ham radio world "it depends". But that's prob what I use the most.

  • @slick8086
    @slick8086 11 หลายเดือนก่อน +5

    At least you're using a chisel tip and not a cone tip like a dingus. But, and this is just a friendly suggestion here, I think you'll have a easier and more enjoyable time soldering if you hold the flat side of your tip flat against the PCB pad and gently push the tip against the leg of the component. If you're lucky and the PCB has plated thru holes this will get the heat into the pad/hole quicker and help to flow the solder better, then the solder will help to heat the component leg and voila!

    • @657bhang

      I think cones are easier than chisel, it's a choice.

      I agree but the main thing I think is technique. Been soldering for fun and professionally for 60 years. I am still learning. Great review by the way. ​@@657bhang
