Yes, I experienced this in Mongolia last year. The wind blows there very
fine dust (as fine as women's power paint) and it creates tremendous static
charge in the antenna. Without the choke I saw it rcing constantly on the
cable of the 26m Titanex. I used a beer bottle and some wire to make a choke
down to the grounding rod using as much wire as I could wind on the bottle.
I checked the Z with an RF analyst and it show no change in feedpoint
impedance.
