Actually, T&B/Sachs makes something similar for Coax. It doesn't use the same wedge system, but looks very similar since it includes the traditional stainless bail (loop) used with telephone drop wire clamps. Here's what they look like:

Just don't pull it too tightly and this will reduce the clamp's pressure on the cable. The ridges or "teeth" will simply bite gently into the cable jacket. Being in Arizona, I doubt that you'll have any snow/ice load to worry about on the cable (correct)?
I have even used these wedge clamps on 14/2 and 12/2 UF cable back in the COCOT (payphone) installation days when we needed power to the remote location. I know it was wrong, but it looked a lot better than doing it the proper way.
