Default 75 Ohms - It's Not Just For TV Anymore

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.


Now, I've always been led to believe that a ratio is a unit less
quantity. I get the feeling that some length of cable is needed here to
get an ohmic value. Perhaps something approaching infinity?
