Hi all,

I am working on an application of transmission lines for use in
magnetic resonance. I know I have seen in the past pre-made
transmission line that has an inner conductor surrounded by a white
insulator ( I think it is Kel-F, it may be teflon) and a copper layer
on the outside. It is quite stiff, and comes in long pieces that can
be bent with a little effort. Does anyone know where I can pick some
of this up? I have been through about 200 google pages with no luck.

Thanks
