Yes, this would work quite well.? In technical terms, its called a Rogowski Coil.? Uncle and amateurs have fed the base of a water fountain using a Rogowski coil as well as feeding trees.? I'[ve never tried it, but the theory is sound!

Hi, Victor.

Not to derail the discussion too much, but the toroid coupling method shown in figure 32 of that link works very well indeed.
Not only is it mechanically very simple and robust, but you can also infer something about the parasitic resistance of your main loop and interconnect to the capacitor.? I.E. once you have the turns ratio for best SWR at resonance, you can calculate the total resistance loading the secondary side of the transformer and then subtract out the radiation resistance.
