  • +1 for building instead of buying!

    Magloop:

    • I used the https://miguelvaca.github.io/vk3cpu/magloop.html calculator, using 1inch coaxial cable, and a soviet vacuum capacitor. picture here

    Delta loop:

    • for 6m, horizontal polarisation: feedpoint at the bottom, impedance match with quarter-wave length of 75Ohm TV coaxial cable.
    • for 30m, vertical polarisation: feedpoint on the side, connected by symmetric line, and a 1:4 current balun.

    Sorry I don't find pics for the delta loops. Please ask if you want more details!



  • A part of this hobby seems to have a focus on rules, and a strictness about abiding by those rules that doesn't speak to me at all. But I've never been attracted to awards, contesting, diplomas. Luckily, the hobby is wide enough for us all to somehow fit into it.

    So I clearly would tend towards "use all available resources", with a hint of "not caring at all actually". :-)

    But of course, if you engage into a contest, then yes, follow the rules.
