[TowerTalk] Measuring Antenna Impedance

[Rex Lint]

John, 

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

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?
