All my radio RG58 is ex-PC upgrades to CAT5 of course.
Complete with buckets of "T"s and handy crimped on 50 Ohm BNC plugs.

Certain bits of test gear use dismembered Network cards.

I've done networking of 20 years (Since AT&T UNIX, Cromix, Xenix on 386 
etc) and NEVER seen a vampire tap or true Ethernet Coax.
Only RG58 "cheapernet"

I've even done Token Ring. :-(
