Default J pole feed

What works best? The standard J pole feed or the way Arrow feeds theirs?


Arrow feeds their "J-Pole" like a Zepp antenna through a 1/4WL series
section. The spacing of the antenna elements are such that a 50 ohm
feedpoint impedance results. The standard J-Pole uses a shorted 1/4WL
stub for matching. The stub is tapped at the 50 ohm feedpoint
impedance. There is hardly any difference in the two designs.
