    Looking even better after the tidy-up. Sharper than I realised. Excellent build Mike 👍🏻

    Looks great on 20m, very little difference across all three antennas & the Loop is only a few feet above ground. Nice build Mike. 👍

    PG Tips should give you royalties for product placement Mike. Good tea. Not Yorkshire tea (as advertised by Sean Bean) but it's our favourite here too. Oh, the antenna is pretty cool too.

    Great videos, just started building a loop to Franks recipe but with an airspace cap and coupling loop ( spooky coincidence ) i'm hoping to use it primarily on 80m so have a 500pf airspace coming my way, but i'll be very interested in seeing your "double copper loop" ! M0awn

    Hello Mike. Did you need maximum capacitance from that air variable? I normaly connect only the stators to each side of the loop; that prevents loses on moving connections. It does reduce your overall capacitance by half though. Was that your intention? Looking forward to the double loop episode. 73 de ZS2VR Vaughan

      Hey Vaughan, yep ever bit of capacity needed, however keep an eye out...👍

      There's a few good deals on EBay out of Russia for vacuum capacitors right now. If postage and the shocking postal service my side wasn't such an issue this time of the year I would be tempted....

    Hello!
    I build a loop antenna with the measures that every body has of 92.5 cms I got 60 inches diameter the loop should be 1/5 of that 12” but I see that you loop is bigger… can you tell me how long is the circunference of your loop and why?
    Thanks a lot

  • @BrockNanson
    @BrockNanson 3 ปีที่แล้ว

    Very interesting! So if I'm seeing this right, the loop does about the same as the other antennas on 20, but is a couple of S units down on 40? I'm assuming that the radiation orientation was the same for both the loop and dipole on 40 m?

    • @mike-M0MSN
      @mike-M0MSN  3 ปีที่แล้ว +1

      Yes and no, when I am on the Magloop, the pre-amp is automatically switched in, without it is 3dB down on all bands but also smooch more quieter.

    thank you for your great videos.
    Just one question. Maybe I missed it somewhere but which version of coupling did you use?

  • @johnpeterson7264
    @johnpeterson7264 3 ปีที่แล้ว

    Sorry I’m confused - that’s a beautiful looking butterfly capacitor but it seems you’ve linked the two stator plate stacks as one and created a commutator to the rotating plate that would normally not have an electrical connection to anything. Won’t that create a lot of resistance ?

    • @mike-M0MSN
      @mike-M0MSN  3 ปีที่แล้ว

      Aah, I have turned a 3 plate cap into a two plate cap using the stator plate as one and the rotator plates as the other..creating a larger capacitor

    Isnt that a ts990 ? 6300£ radio and the dsp still makes that watery sound. 👎
    a yaesu ftdx3000 has better dsp and that thing is for 1400£ new.
