John,
The impedance repeats each 1/2 wavelenght, not 1/4 wavelength.

Subject: [TowerTalk] Measuring Antenna Impedance
I want to measure the impedance of an antenna and it is not practical to
connect an antenna analyzer directly at the feed point. I believe this can
be done using a 1/4 wl section of coax. Can it be done with any multiple of
1/4 such as 1/2 wl, 3/4wl, etc?
