Of course if I viewed the world through a 80 meter dipole at 50 feet

on all those commercial systems, I might agree with Cecil.

When the only tool one has is a corona hammer, all problems
look like corona nails. Fortunately, I am familiar with both
corona problems and dry-air wind-driven charged particle
problems.

All the problems I saw related to corona.

At least that's what you assumed. Just because all the cars
parked in your driveway are white doesn't mean all the cars
in the world are white.

Whether it's dust, snow, or the atmospheric electric field charging the
antenna, the noise is still corona discharge. At least that's what most
of the sources say. Tom says height makes all the difference. That would
make a lot of sense given the way the earth's electric field is structured.
