For the reasons  given in other posts, I wouldn't trust it.

One thing I've seen with RG174 is migration of the center conductor 
caused by I^2R heating where the cable is bent into a small radius. It 
does not take much shift to cause a center conductor-to-braid short.

If you have to use a small diameter cable because of physical 
limitations, I would go with a Teflon equivalent, such as RG-188.
