[TowerTalk] Teflon Coax with Center That's NOT SCCCS?

[Jim Brown]

All the 0.195-in o.d. TFE coax cables I can find have a center conductor 
that is silver-coated copper-coated steel. This is fine above HF, but 
it's not great for 160M and 80M, where the steel is contributing to loss.

Can anyone point me to a 50 ohm TFE 0.195-in o.d. cable whose center is 
NOT coated steel?

Likewise, they all have a solid center with a 2-in bend radius. Anyone 
know of one with a smaller bend radius?
