    I apologize for getting back on topic but does anyone know how much power this antenna should handle?

    Not more than 5 Watt while tuning that close to a loop.....

    The power handling is a function of the distance between the capacitor plates at the top. In addition, other factors come into play such as humidity, dust etc. However, it is safe to say 100 watts wouldn't be an issue, and would handle more.

    Interesting video, thanks ERIC for the presentation and explanation.
    I will look for more info and I would like to try this loop in my qth.

    It's funny that a thread goes 4 pages deep for a glorified dummy load on a band that is dead as a doorknob, but a good QRZ article like this is growing cobwebs.
    At least people are home-brewing though!

    Have you tried using an STL on 6m? Or any band?

    Obviously not! Ignorance is such sweet bliss...

    And it explains why STLs have such a poor reputation -- gossip.

    Yes, indeedy. I'm going to let the naysayers have their fun; STLs will remain one of the best kept secrets of the compact antenna world---and that's OK by me.

    The so-called ham antenna community isn't exactly nurturing. Who needs the abuse?

    Looks like VE3UK used a CNC machine to cut it....nice.

    If you had dictated that size and searched for solutions, you would have found a Minkowski fractal would be somewhat bigger (oh, 25+ inches) but cost about 80 cents, and five minutes of patience with a 3-nail jig. 50 ohms, 2+ Meg bandwidth, 2+ dBi.

    But hey....STL's look more like the plastic crystal radio/antennas we used as kids, so they must be cool....and we love living in the past :-( Same old antennas, (usually)derivative PRC-made tools to get there. Such is 'innovation' in ham radio in the modern era one supposes.

    It USED to be fun to work with our hands, and minds.


    Anyway, if you WANT an STL on 6m, this is certainly an elegant one from VE3UK.
