In studying for the Technician exam I am finding questions which seem to
be making a big deal of having sharp, right angle bends in the ground
wires for lightning protection. I know that for digital electronics the
old warning about right angle bends has been shown to be pointless up to
many GHz. What is the deal with lightning? What happens when the
ground wire is bent in a right angle? Has this been verified by
experiment anywhere or by application failures?
