same thing in the NEC (the building code, not the software) - there have 
been several wording changes to make it more clear - that whole 
grounding conductor (green wire)  vs grounded conductor (white wire -

It does take years. And I'm sure all hams use nothing less than 12 gauge 
hard drawn copper for their 80 meter dipoles - you could get away with 
14 gauge for 40 meters, because 66 ft is less than 75 ft.
