    Clarification on a couple of points made in the video: The wire used for the CHA 40 20 FD is 16ga Kevlar PTFE, not 20ga.
    As for tuning. The antenna is intentionally cut a bit long so it naturally resonates towards the bottom of the band. Wrapping the wire on the winders allows you to field tune the antenna to your desired frequency and there is a chart and instructions in the documentation on how to fine tune the antenna.

    I made 2 dipole antennas for the home QTH and attempted to make my own fan dipole. Having both elements tuned correctly is definitely a feat of patience as when they were connected the measurements for both bands were thrown off. I may possibly revisit the antenna to cut back on co-ax runs and clutter in the trees... But for now I have 2 antennas on the same hoisted center point. Good review and video!

    I have made a Fan Dipole Antenna for 20 and 40 meters and it works very well I have had contacts world run on 25 w ft8. LA2VLA 73

    Thanks for a very thorough, fair and balanced product review, Michael! It does seem a little on the pricey side at $200 - but there is certainly a value to a mostly unbox-and-go antenna.

      I've found that value can be relative. For what it is, it's well constructed and works. Glad you enjoyed the review.

    Great antenna man. By the way I was waiting to ask you an important questi- SQUIRREL!

    Thanks for the video. I think this is a pretty fair review.

    This is literally just some wire, an RF connector, and some screws/plumbing pipe/caps....for $199. Sounds like a great deal!

      Doesn’t it have an inductor inside as well?

      You are also paying for the engineering, testing, assembly, quality assurance, documentation, support, and time that could be spent on other tasks instead of building yourself. Those things are valuable.

    Its well made but a fan dipole for 200 dollars is pretty expensive.

      It is a bit pricey, but I've found that value is relative.

    awesome video as usual, also i just seen your tape measure antenna video and was curious if you would be willing to make a tape measure antenna for GMRS i want to build one but dont know where to begin

    • @tylerdean980
      @tylerdean980 3 ปีที่แล้ว +2

      The idea is the same, you just need to make it the appropriate length for GMRS. Pick a particular frequency and do the math. A good idea is the middle of the band. There are yagi calculators online that will tell you the length you need, and the spacing between the elements.

      @@tylerdean980 thanks for the info much appreciate i just love experimenting with DIY antennas but always afraid of blowing equipment up lol but i will look more into for sure thank you very much

  • @kareneighth6045
    @kareneighth6045 3 ปีที่แล้ว

    If 20 is resonant at 14.3, it would require lengthening for Cw part of band? If so, not good and I would not buy.

    Wish you would have given your opinion of the price. Seem a little $$$ to me. Seems a lot for that type of antenna.

    • @KB9VBRAntennas
      @KB9VBRAntennas  3 ปีที่แล้ว

      I typically don’t comment on the price as everyone perceives value differently. What I may feel as affordable may out of line by another.
