The JPC-12 - Third time's a charm?

Published 2023-06-24
The comments kept on coming on my last video, including one from @LA5PPA / Lasse with some instructions on how to tune the antenna. Also ‪@HAMRADIODUDE‬ made a video inspired by my attempts on tuning this antenna, so I had to give this another go.

Could I get it to tune now?

Should you wish to take a closer look at the antenna you can buy it all over the internet. This is an affiliate link to AliExpress: s.click.aliexpress.com/e/_DEPQi2z

    So glad I watched this, I had totally forgotten to stay hydrated with setting up my antenna. Super useful information.
  • @slorznovitch
    Finally found a reference for 10 meters. I would have never thought of removing the rods and coil and just using the whip. Thank you!
  • Found list in comments! Thx👍🙏 ps they are at 3 months postings!
  • @HAMRADIODUDE
    I'm glad you did give it another go, regardless. Good job.. enjoy the POTA . I'll be hydrating

    Top marks Morten for persisting with the antenna rather than just thowing it in the "too hard basket" and writing it off as a faulty product......it shows the hallmarks of a reviewer that your viewers can trust. Cheers ZL2VTH

    Extremely useful video for a new JPC-12 owner, thanks a bunch. 73 from Paris, France.
  • @DNL1200GSA
    Thanks for the video. Great explanation and instructions. I had mine working for the first time today. It’s fiddly, frustrating and now you’ve motivated me to persevere with it. Thanks. I’ve just subscribed! 73

    Many of those matches look more broadband than I expected. I’m going to buy one. I really don’t mind any extra tinkering. Every location has different ground conductivity and surrounding objects, so most similarly constructed antennas will give a similar experience. Most modern radios show SWR so its pretty easy to trim. Thanks very much for the good info and hi-res video.
  • Where are these instructions at in English, can't find them, would love to print them out ! Thx for doing this video,very helpful 👍🙏

    Good video. It is always good to see people be able to work out technical issues that they are having. I am a big believer in KISS method, so I get your concern about this might be to much for a new ham. I just release a video myself yesterday on the antenna. I am looking for an antenna that was small and compact that I could take on a trip out to the desert. I got great results with it on 20 and 40 during a POTA activation in Indiana. I banged out 50 voice QSOs in an hour across the US and Canada with 2 of them in Europe. The only issue I had was with the provided radials, but once I split them apart, the SWR came in to line. I will be replacing them with some homemade ones.

    Good luck on the POTA event. 73
  • @robpinter5431
    Thank you for the video, has anyone posted the tuning instructions for download?
  • @PhilG8PJH
    Have a look at KB9VBR , he uses a aluminium window mesh instead of radials, I tried it with my portable ground spike and 17 foot whip, and it tunes all bands from 20 to 6 like a dream just by adjusting the whip length. With my slide winder it will do 30 or 40.
  • @mikedodds7547
    Any ham that likes tux cats is OK by me😀 And the antenna video was good too!
  • @EA4EVK
    Hi there! Could you tell me where to find that sheet?? I’m my instructions manual doesn’t come so many configurations. 73!
  • @NamasenITN
    Your furry helper might introduce strong em fields, as he started moving after you pet her.😂
  • @tcwaite88
    Where did you find the cheat sheet that you are referencing in the video?
  • @John_Henry83
    Did you ever try this antenna out in a actual POTA activation? Where can we find that list to tell you how to tune the antenna on different bands,.
  • @fjrempel
    This helped. Thank you. 73, KK7BN
