note that the shape of the conductor is
very important in this process also, a blunt smooth surface will produce
smaller fields and have a higher inception voltage than a sharp point
because the field gets concentrated more around the point and thus requires
a lower voltage to start corona breakdown.
So the sharp ends of a single-wire dipole would be more
conducive to corona than would a rounded full-wave loop.
Would you say that an antenna without corona is quieter
than an antenna with corona?
