I understand what you said, but there's some muddy thinking. If 
you're thinking lightning protection, remember that MOST of the 
energy in lightning is NOT DC, it is predominantly RF with a DC 
component. The ENERGY in lightning (what fries things) has a VERY 
broad peak centered around 1 MHz (and if you operate much 80M, your 
ears tell you that there's still plenty up there). A DC connection 
has little relevance to lightning. What matters is the RF path for 
lightning induced current. 

Again, I strongly urge that you study what I have published.
