    Very Nice! I’m gonna redesign this for NVIS and use it at 100W with an air
    varicap. Did you try it at a horizontal position?

    Drawback to air variables: arcing is VERY possible at anything above QRP
    power levels. There are thousands of volts at the capacitor. Air variables
    that use wipers will have high losses, as well as limit power levels.

    I love your design. I have worked you twice and experience the otherside of
    the two element. The gain is really directional when you turned the antenna
    at me it really improved. One of the strogest signals from your area. Im a
    believer, good work. K5BAK

    Hi, Very interesting work you are doing. Just curious if you have tried a
    single element loop on one of the high bands compared to your mag loop? It
    would be very interesting to see how your magnetic loop compared to a 2
    element quad.
    Thanks for posting your work.
    73,

    Very good video clips and demo, but I have a dumb question: Can’t seem to
    find this available for sale or even any info on it? Is it on production,
    and where can I get one…in the U.S? I assume this is more broadband and
    would be good for FM as well as SSB/CW part of the band. Tnx es 73
