antenna impedance - calculated 10 - 20 Ohms - measured 36 Ohms??

I have measured the antenna with two different instruments. One is an
Autek analyzer at the antenna, the second is with an 8405a at the end of
100+ feed of cable. They both show the same results.

Are you aware that a coax cable will change the impedance
from the antenna feedpoint impedance in a spiral to 50
ohms in the limit?
