>Is there a such a thing as a coaxial surge suppressor?
There is. Your cable company is supposed to supply that on their end. I got one of pic after a storm blew up some stuff through the cable line. They're not cheap but they're made in Florida, so they probably lightning serious. Fuck the cable company's CPE. If they don't want to protect it I have no problem bringing them dead modems.
