While serious lightning protection for structures and other
robust things must be done outside the building, I have heard
reports of K3S USB chips being fried from currents induced in
the USB cable attached to the radio, with the suggestion of
disconnecting the cable to protect the chip. I don't see how to
do this disconnect outside the building.
When I consider a direct strike on my shack's lighting rods, I
see massive currents flowing down the thick aluminum cables from
the rods to the grounding system. I see these currents inducing
currents in any wires in the house, including the USB cable. The
lightning rods are the first level of protection, but may not be
enough to protect sensitive electronic equipment. Remember, when
we work on these radios, we have a grounding wrist strap and a
conductive mat on the work surface etc.

for one minute that one can provide lightning protection inside
the equipment or structure.
