Topband: RG-6 questions

Tom,

I guess you meant to say that "Type HN and others, including UHF, are far more suitable for high voltage operation."

I better correct two pre-coffee typos I made:

This means modern RG6-type (which was also called "F6" and isn't a real RG6 
military number with copper shield and solid dielectric), if it does not 
have a serious internal flaw, at even a remotely reasonable SWR, is heat 
limited.
