Yes, it definitely helps with rain static. If W8JI actually stated that
grounding the elements doesn’t help, he was wrong.
It is important to bring both sides to ground, and together, usually through a
large value resistor or RF Choke that will handle the power. Tieing both sides
of a dipole through this to ground provides a path to bleed off the static
charge, thus eliminating rain static (and snow static, etc). As Wes stated,
adding a fairly large resistor across the dipole insulator really helps. Then
timing that to ground through the arrestor finished the job.
