[Elecraft] Special type of coax - need info

[Bill]

30 years ago, when I was living in Fairfax County, VA, the TV cable was 
shipped around on a double coax cable. It resembled lamp cord or zip 
cord, and was two parallel coax lines with a webbing between them. I am 
in need of the proper name for that cable, so I can search some out.

I used it as feed for a full size lazy 80 meter loop - about the same as 
tuned feeders would be used. It worked very well on all bands - 
providing lots of DX and a ton of local coverage also. Not a tri-bander 
- but it beat the socks off other wires and verticals. I want to 
duplicate that antenna this spring.

Thanks,
