All through this my IAC double bazooka was no quieter than a regular
dipole made from #16 bare copper located 100 feet away at the same
height.

This test was with all antennas in place at the same time on the same
day in the same weather.

Precipitation static doesn't always occur during thunderstorms.
It's effects are greatly reduced in high humidity environments.
For precipitation static to occur requires charged particles.
And you don't know if charged particles even existed during
your experiment. To separate charged particle effects from
lightning effects you need to run your experiment without
the clouds and thunderstorms under conditions that guarantee
charged particles. That would be during a dust storm on a clear
sky day under low humidity conditions as often exist in Queen
Creek, AZ.

Precipitation static is a large problem for airplanes but
only when they are flying through a field of charged particles.
One of the treatments for precipitation static on airplane
antennas is to insulate the antenna inside a non-conductive
pipe. Another treatment is to fold the antenna. These are
well known, well accepted methods of reducing precipitation
static problems on airplane antennas. You can verify those
facts for yourself through a little web research.
