[FONT="]What Code reference requires CATV ground rods to be connected to the building service ground rod, as one method of tying the two systems together?

Okay I thought this question would be extremely easy...What am I missing! Can't seam to narrow down to one single answer
So 820.100 is Cable Bonding and Grounding. The shield of a coaxial cable shall be bonded or grounded as specified in 820.100(A) through (D).
Now if you go down to 820.100(D). It says... A bonding jumper not smaller than 6 AWG copper or equivalent shall be connected between the community antenna television system's grounding electrode and the power grounding electrode system at the building or structure served where separate electrodes are used.
Now for 830.100. Cable, Network Interface Unit, and Primary Protector Bonding and Grounding. Network interface units containing protectors, NIU's with metallic enclosures, primary protectors, and the metallic members of the network-powered broadband communications cable that are intended to be bonded or grounded shall be connected as specified in 830.100(A) through (D).
Going down to 830.100(D). It says... A bonding jumper not smaller than 6 AWG copper or equivalent shall be connected between the network-powered broadband communications system grounding electrode and the power grounding electrode system at the building or structure served where separate electrodes are used.
Now 810.21 says...Bonding Conductors and Grounding Electrode Conductors - Receiving Stations. Bonding conductors and grounding electrode conductors shall comply with 810.21(A) through (K).
Okay and 810.21(J) states: A bonding jumper not smaller than 6 AWG copper or equivalent shall be connected between the radio and television equipment grounding electrode and the power grounding electrode system at the building or structure served where separate electrodes are used.
Hope this helps! I think 820.100(D) is the answer because it talks about coaxial cable but still I'm an apprentice and don't understand terminologies too well I guess. I don't really ever work with CAT5 cables at work.
