Hi Gary,

No, that is one of the neat things about a folded unipole, the sine of
the reactance is reversed from that of a series fed antenna element. The
short folded unipole can be viewed as being a section of transmission
line which is less than a quarter wave, and shorted at the far end. It
exhibits inductive reactance.
