Somebody was talking about ABS accumulating static quickly. Got me to thinking about our vacuum system at work, it is schedule 80 PVC I think, but any time you need to change a filter it will zap you good when you touch it. Was thinking about making something like that to use a vacuum cleaner to pull air through a double walled container.
Apparently air moving past anything leaves a static charge ? That is why antennas are grounded ??
So I needed a way to discharge the static charge which can build up in the antenna. Antenna acts a a capacitor against ground. The 80m 1/4-wave vertical antenna capacitance is in the order of 100-200pF. Snowflakes and rain can and will carry a charge and charge the antenna (capacitor)
