Hi Bob,

I appreciate your answer, but I never accept one source 
(especially without an explanation of how the information was 
gleaned) for critical data. 

Can you recall the  source of your information, or if second hand 
where the original source of the information can be found?

You seem to be implying lightning is a square wave, with a 2 uS rise 
time and a perfectly flat or insignificantly sloped top.

I've read lightning is composed of a series of events of differing 
polarity and levels.

What is the source of information that lightning damage is from 
steady dc current?

What is the voltage rating of the capacitor, and the capacitance 
value?

Is there a shunt impedance at the rig end of the surge protector?
