Having just spent time explaining to a guy named Yagi that his name was famous, I had two hours on trains to ponder the snow static thing. Because the quad avoids the corona problems of the yagi and

On static bleed paths... The charging current should be quite low, since the antenna is physically fairly small. The cases reported in the literature of continuous sparks are from things like miles o

Of course the gradient is real, and very measurable... even in clear air. Even with no storm around there is a gradient that can be easily measured and a current constantly flowing from the ground th

It's not charging from the air, it's charging from the particles, which DO have a potential relative to their surroundings (i.e. the air). The potential is defined by the work required to move the ch

Have you ever made observations of this charge buildup under varying humidity? I am wondering if higher relative humidity decreases the charge potential and vice versa. Keith NM5G corona? I never sai

high humidity increases the breakdown voltage of air, increasing the amount of charge that can be carried by a given sized particle or object. high humidity also DECREASES the surface resistance of m
