I think I may have confused things by throwing the trade name "Twinax" into
the equation. The stuff we used with Wang computers and WP gear was more
like 2x RG59, 2 1/4 inch coaxial cables in one molded jacket. I don't know
what the impedance was. It was terminated with ordinary BNC or TNC
connectors, and was reasonably flexible -- better in that respect than a
single RG-213. Some of it was Teflon jacketed, and approved, I believe,
for installation inside drop ceilings (at least, that's where ours was).
