Peter, Mike, I think Elecraft does a reasonable job at protecting equipment inputs. For lightning protection, there is much literature on methods and practices. A principle to keep in mind is protect at the “point of entry”, the desk setup, the entry to the house/shack, etc. Another is proper grounding of the equipment, separate from the cabling. Optoisolators for USB, surge protectors for Ethernet, surge protector power strips for AC (I like Tripp Lite Isotel) are all part of a in-depth, layered defense.
Since protection is a system level problem, what can be done at the component (radio) level is limited. Don’t forget the antenna feed line itself.
