I seem to remember an article about someone taking a full-wave
horizontal loop antenna and making two loops (or was it a half-wave
loop?). The second loop caused the antenna to match 50 ohms so it
could be fed with coax and (I think) it operated multiple bands.
Anyone remember this article and know where it might be?

Hi Buck,

It is a small tuned loop (less than a tenth wave) with a smaller loop
(about a third to a fifth in size of the first loop) inside it.

Not much else to say except that polarity is vertical/horizontal when
the loops are in the horizontal/vertical plane. Make every effort to
build low Ohmic connections and elements. The capacitor will have to
stand off a high voltage (and many caps suffer from ESR).
