Coax cables with velocity factors of 0.66 are in wide use. And in
some very specialized areas - especially the world of delay lines -
coaxial cables with velocity factors of less than 0.10 are used.
These cables are extremely expensive and somewhat fragile, as their
center conductor is a coil around a ferrite core,
rather than a plain copper wire.
