But that is my concern.  An F connector simply attaches to a wispy braid using a crimp connection.  The RG6 I'm using, which I assume is characteristic of all RG6, has the braid coated with a sticky goop as well.  I've never used coax with a sticky goop on it.  

I was hoping to find a resource that indicated a power rating but have been unable to locate any references to power handling--only loss characteristics.  It would be nice to actually engineer a solution rather than use empirical evidence.  For example, the 5KW was pumped at a pretty low SWR.  What happens at 2:1 or 3:1?

The RG6 is appealing because the feedpoint in this application is around 75 ohms, and the line must be suspended horizontally for about 32'.  RG6 is so incredibly light weight, it appears to be a perfect solution except for the lack of a QRO rating.

Thanks for the responses.  This may be one of those applications where you just build it and see if it can be 'smoked.'
