? What is the "Ohms" Measurement associated with Antenna Impedance ?

A ratio between the inner diameter of the outer conductor and the outer
diameter of the inner conductor.


I've tried manipulating my twin lead cable into that configuration, to
no avail. The best I can get is something resembling a double helix. If
I leave it twisted like that, it may have genetic ramifications.

For parallel lines it's diameter v distance. Common zip cord is ca. 75
Ohms.
