Can't be true as it is not printed in a book !

Whoa there, Art. There seems to be confusion between
two topics. As far as I know, there is no obvious
difference between the precipitation static levels
on a horizontal Vs vertical antenna. That this
particular antenna is vertical is mostly irrelevant
to the alleged precipitation static problem. It could
just as easily be happening with a horizontal antenna.

The fact that the noise might be attributed to something
other than precipitation static might involve vertical
polarization but I don't think precipitation static has
much to do with polarization. A wind-driven charged
particle is just as likely to encounter a vertical wire
as a horizontal wire.
