And the National Electrical Code is a required minimum standard in most jurisdictions in the USA.
bear in mind that the NEC (NPFA 70) is different than the Lightning Protection Code (NFPA 780 - STANDARD FOR THE INSTALLATION OF LIGHTNING PROTECTION SYSTEMS).
NEC doesn't mention anything about lightning rods, air terminals, etc.
NEC (and NFPA 780) require that the lightning protection system (LPS) and the structure's electrical system ground be bonded together, but interestingly, they also require that they be separate systems: e.g. you cannot use the electrical safety ground conductors (green wire) as lightning safety ground. Nor can you use your lightning protection grounding conductors as a electrical safety grounding terminal.
The antenna grounding requirements in the NEC are more about contact with power lines than lightning protection: the bonding is all about making sure that nothing you "touch" is at an unsafe voltage, so you can wander about in damp bare feet without fear. It's also about making sure that the fuse blows or CB trips if there's a short between power line and "touchable" stuff (e.g. metal enclosures, water pipes, fixtures).
Which is why I used the word minimum.
Here is a link to the book in pdf. www.uscg.mil/petaluma/TPF/.../NFPA_780.pdf
Interesting but geared to setting up a lightning protection system. Not for properly grounding your equipment and feedlines. The section on tower protection is interesting, and requires further study to see what would be proper for ham towers.
However it does not relieve you of conforming to NFPA 70, since all residential units in most jurisdictions in the USA are required to comply.
