In the audio video world, it would depend on the damage, and if it extends to the core. If it does, you can cut, strip, and splice and it's not a "huge" issue. Now, if I was installing a $100k projector, I would replace it and never look back.
I'm just not familiar enough with HAM or CB to know how sensitive that antenna feed actually is to splicing, or even just taping over the insulation damage.
