grounding of sat dishes/ Antennaes

[sparks27]

I'm looking for an article on grounding the roof vent mount. TV antennaes or the small 38" sat dishes. All I could find was 2005 NEC art. 810.21 (K) not smaller than #10 copper, take to nearest cold water pipe, this is Multi family Dwelling. Thanks,

What year code are you using?

Under the 2008 NEC you should connect the grounding wire to the intersystem bonding terminal using a #10.

You are correct in using 810.21 as your code reference for grounding of satellite dishes.
