Just a little thought experiment.

Something else that I have wondered about:
Given a threaded rod with about double the surface
area of a piece of tubing, does the VF decrease?
Can a threaded rod be used to decrease the length
of a resonant vertical?

hmmm, interesting thought. I know where I can get a 8 foot threaded rod
of the same diameter as a solid rod. Maybe an experiment in the works.
