Now it's not so obvious that it might have classic dipole radiation
Thinking that a loop is like two dipoles in parallel, is a real stretch.
And in fact a good 1 wavelength loop radiates nothing like a dipole!
Bend a circular loop into a square or triangle, and it's not quite so
omni anymore; but it's still close enough for government work.
