Does this antenna have an upper limit on the frequency it'll operate at?
I'd think some real life data on efficiency could be derived from enclosing
anantenna in a 'big enough' styrofoam cooler type enclosure. If the parts
that *I* suspect to be lossy might cause a significant temperature rise with
several hundred watts fed to the antenna.

No report , that I am aware, of Wheeler cap measurements. Antenna is
monochromatic and moderate/hi Q.
