I am not exceeding the manufacturers ratings.
NOTE: Times Wire ratings on their page.
For example, LMR-240:  Peak Voltage rating 1500, power max 5.6 KW
LMR-400:                       Peak Voltage rating 2500, power max 16KW

With RG8X you have to depend on the ratings of the individual 
manufacturer and they may vary quite a bit, but good cable should be 
close to the voltage ratings of LMR-240.
 
At resonance this should be no where near the max ratings at the legal 
limit.  Even with the antenna resonant at the center of the band at the 
inductive end of 75, the voltage would still be within the ratings.
