Default Noise level between two ant types

Particle discharge makes radio static noise.

Look at Terman`s description of "precipitation static". Instead of
charged particles blowing in the wind and alighting on stationary
antennas, Terman describes aircraft and their antennas flying through
clouds of charged particles. The effect is the same.

Terman`s solution: keep the antennas away from sharp points on the
aircraft which tend to noisly discharge the aircraft, insulate antenna
wires, and put Faraday shields on the directional antenna loops.

I've done a bit of googling on the subject, and find that most seem to
favor this sort of explanation of the phenomenon. A notable exception is
W8JI. To Tom's credit he performs some experiments along those lines.
I'm not completely sure that I buy the conclusions, but I'll digest them
a bit more. I would suggest that Tom may want to experiment with
charging dust particles with that HV source rather than water.

Some have suggested that Cecil's statements are invalid because he
hasn't done the experiments - not so. His view represents the
mainstream. The debunkers have the burden of proof.
