Maybe. RG-188A/U (Belden 83269) might be a bit better, it's rated for 
much higher temperatures (to 200C), and has slightly less loss (vs. 
Belden 8216 RG-174/U).

There's this: http://www.therfc.com/powerrat.htm#RG174 Says 174 is good 
to 160W at 50MHz and 188 to 480W at 50MHz
Then this: www.qsl.net/va3iul/coaxloss.pdf Says 174 is good to 
95W at 145MHz and 188 to 380W at 145MHz

The two sources roughly agree. I assume that they assume a 1:1 SWR.
