I don't currently own a cf mast, so not my first worry, but it is that of the OP.
I recently read up about lightning mitigation and learned some interesting details.
Rasputin is right with the angles: electric current prefers to go straight, so if your system makes an angle it might jump to another "ground." Ideally it goes straight from the top of the mast to the keel. Some...
