   And which myth is that?  A "J" pole IS a vertical, end fed dipole,
which perform as well as a quarter wave ground plane, but require no
radials whatsoever.
   Many others and I don't make "J" poles "fed with coax as is the
current style" we feed it through a quarter wave sleeve balun or we
bend the "J" pole 90 degrees between the stub and the dipole. So there.
