[BC] Wave lengths (has migrated to coax construction)

[Dave Dunsmoor]

All this discussion on velocity factor, then coax construction caused me to
wonder,

1)    could a broadcast version of triax be built,

2)    would it be practical and,

3)     would it be useful...?

Triax being the inner conductor of the 3" or 6" coax being hollow, could
then have it's own inner conductor to comprise a second coax of much smaller
size... to be used for STL, Marti, whatever....
