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?

of course. we see that here all the time, the top antenna of a stack can be
very noisy with corona, but those lower down on the tower (even though they
are getting hit by the same rain/snow) are quiet.
