[Kenwood] Lightning protection wire antennas WA8OPR

Thu May 15 12:21:22 EDT 2014

I had not thought about my concept being to remove static buildup.
It is what I get for trying to go by memory!
It seems to fail me more and more as time goes by.
The lightning protection I have in place is 1/4" solid copper with a 
stinger several feet above the top of the chimney. It comes down and 
goes to several 3/4" Copperweld ground rods, and these are bonded with 
heavy copper cable by brazing to the rods. I also used large split 
bolts to additionally attach the heavy cable. It is my insurance to 
keep the brazed joints from coming loose.
Never have sharp bends in a ground like this! Lightning tends to depart 
a ground system when the angles are sharp. Always use gentle sweeping 
bends, BUT do not make this conductor too long!
