One must question the charts.  I don't see two antennas having
identical gain (to 0.01 dB), F/B or F/S, or SWR Bandwidth on
every band.  In fact, the SWR curves published for the two
antennas show the 1.5:1 and 2:1 bandwidth is *different* for
the two antennas even if they adequately cover each band.

73,
