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

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.
