[TowerTalk] FYI: Antenna wire and the NEC

[Alan NV8A (ex. AB2OS)]

Excerpted from

http://www.arrl.org/files/bbs/general/nec_code

"Antenna wire size: (or lead-in size)

less than 150 foot span-hard drawn copper 14 awg minimum, copper
clad steel 14 awg minimum.

greater than 150 foot span-hard drawn copper 10 awg minimum, copper
clad steel 12 awg minimum."

Note: either "hard drawn" (which the stuff used for house wiring isn't) 
copper, or copper-clad steel.
