Article 300 does not apply to low voltage and communications wiring covered by article 800 and beyond unless it is specifically referenced. Read from the beginning of the book. There is nothing in the NEC that stipulates support distances for communications cables. This is a design and installation issue.

If your electrical inspector has something to say about it he must cite the article in the NEC (or local ammendment) that he believes is not being followed. He can't just make things up or decide he doesn't like something.
