Commerical audio cable is typically a twisted pair in a vinal jacket
depending on application. I've never tried the twisted pair for a
transmission line but my DX-35 almost never saw coax. It loved the old zip
cord with one conductor stuck into the SO-239 center hole and the other tied
to chassis. circa 1958....... regards, Bob K4BG

The problem with Lamp cord (Zip Cord), certain speaker cord, it does not
stand up to the sun light, and it is lossy from what I have heard.
Zip cord as far as I can remember has always been used for speaker cord.
Very few lamps these days use it, mostly speaker wire. UL has been
requiring 3 conductor cable cause of the ground wire requirement.
