Hi Steve, I have used twisted lamp cord and currently have a reel of smaller twisted pair. I increased the twist and use it as feed line for a small loop around the edge of the ceiling in my radio room. I use it for receiving as well as transmitting at low power levels. Twisted pairs have been used that I have read about since before WW2. The cables you talk about have advantages over the simple twisted pairs I have used. Thanks for posting this.
