[Elecraft] OT: pwr rating of RG6, etc

[DOUGLAS ZWIEBEL]

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.

PS...you can always paint black coax using exterior paint.  Mine gets
painted "for free" every time the house is repainted.  LOL
