And another thousand points for answering the question--which was about the
cable's specs, NOT ABOUT ITS APPROPRIATENESS FOR A SPECIFIC APPLICATION.

Your posting appeared on usenet different from your own intention.

From your posting:

"How does this affect the performance? I'm looking at 1 GHz (HDTV use)."

That clearly is a question about appropriateness for a specific application.

You did not ask about the loss, you asked about the performance. So
that means "they may be loss, but does it affect the results". The
answer clearly is: it depends on further details, like what margin you
have on the signal.

Shouting does not help you, just face the facts.
