Well, the imprdance I qupted was the radiation resistance, which is the
voltage to current ratio of an antenna at the maximum current point in
the antenna. I was just too lazy to post the complete Table given by
Bailey.

Only when the order of resonance in a center-fed dipole is odd, 1st,
3rd, 5th, etc, is the feedpoint resistance the same as the radiation
resistance. In odd-ordered resonances, the antenna feedpoint resistance
is te same as the radiation resistance. In odd-orfered resonances, the
antenna feedpoint is at s current loop.

In even-ordered resonances, the value of the feedpoint resistance is
equal to the feedpoint impedance squared, divided by the radiation
resistance value. Bailey has worked it all out for us.
