I think you mean RG-174 coax, here's a great article about using this coax,
but I didn't find anything about it's power handling.  BTW, my Diamond
antenna mount for the van uses this coax and has no problem running 100
watts from my FT-900.
Here's the article:

Hi

     I recently installed a long wire by running it through an open window
and then closing the window on it. I then realized that I could do the same
by using a piece of RG 74 as a jumper and using heaver coax on either side
of the jumper. How much power can I run through RG74 and what is the normal
impedance of this coax?

God bless,
