That is true, but a resonant, helically-wound, electrically short
radiator does *not* have the radiation resistance of a straight, self-
resonant radiator of about 1/4 wavelength -- which can make a large
difference between the two forms in the amount of available energy
radiated vs. that lost in the r-f ground system.
