Are primary protectors required (2008) for CATV entering a building?

[richwaskowitz]

820.93 says that "where installed" they must be listed. Where does it say that they "must be" installed or required?

Read the rest of that section for your answer.

I guess I'm thick. I still don't see IF they are required. Could somebody else help?

The way I read it, where you install Cat V you have to have a listed primary protector.

Primary conductors are not required as long as the outer shield of the coax is grounded at the building.

820.93 Grounding of the Outer Conductive Shield of Coaxial Cables.
Coaxial cables entering buildings or attached to buildings shall comply with 820.93(A) or (B). Where the outer conductive shield of a coaxial cable is grounded, no other protective devices shall be required. For purposes of this section, grounding located at mobile home service equipment located within 9.0 m (30 ft) of the exterior wall of the mobile home it serves, or at a mobile home disconnecting means grounded in accordance with 250.32 and located within 9.0 m (30 ft) of the exterior wall of the mobile home it serves, shall be considered to meet the requirements of this section.

Thanks Don. That was what I got out of it but was just looking for a little confirmation.
