[TowerTalk] Quad elements no rain static.

"Regarding charge accumulation from water and snow landing on the antenna, there is a lot to learn from the aviation world. However, aircraft are certainly contacting enormously more charged particles than precipitation landing on an yagi.  What is interesting are the devices added to aircraft to dissipate the charge and eliminate radio interference."

While some charge accumulation on planes may be due to transfer from the relatively highly charged drops in convective storms, I believe much of the charge that is dissipated by those devices is due to triboelectric charging.  This is also the mechanism for creating corona in dry windy snow or desert conditions where there is no convective storm nearby.
