Top banders use RG6 all the time and run full bore (and then some) through it. At 1 Mhz, it is rated at 4kw.
If you're only interested in 100 watts output (you didn't say what frequency you operate), you're good to go with RG6 up to 1GHz. The "white stuff" is so cheap, you can replace it every 5 years if you want to be conservative with concerns about UV deterioration. http://www.therfc.com/powerrat.htm de Doug KR2Q PS...you can always paint black coax using exterior paint. Mine gets painted "for free" every time the house is repainted.
