Re: How do you measure a car antenna?

 

Car radio antennas used a 'Motorola' connector. Motorola invented the car
radio, when the company was still known as ' *Galvin Manufacturing
Corporation* '. It became Motorola in 1930, to signify their car radios.

Car radio antennas are a 'high impedance' design, and their co-ax cable is
also Hi-Z.
While 'any antenna' will radiate, some do it FAR better than others.

To more directly answer your original question, you would need a cable
with the proper connector to connect the antenna to the vna. Do you have
one? As I recall, older car radios use a connector like the old RCA phono
plug/jack system. A push-in coaxial plug to fit the car's jack. Get an
extra car antenna with cable from a junkyard, cut off the 'radio' end and
use the cable with the vna.
