You are correct but I wouldn't consider using it for transmitting on any 
radio with power more than about 25 watts.

The original RG 6 was made well but today finding a consistent quality 
cable is almost impossible unless you buy the best US specified brand, 
which is almost as expensive as LMR type cable.

Even then, you are taking a chance if you try to put much over 25 watts 
into it.
