Cable already installs the best protection for cable. Cable earthed where it enter the building by one wire (ie 'less than 10 feet'). That earthing (not any protector) is the most superior cable protection. For other incoming wires (ie AC electric), also have an earthed 'whole house' protector. That and no other protector is by far the best and least expensive protection for your computer. About $1 per protected appliance. That is also what every facility that cannot have damage does. They also do not waste big bucks on that adjacent protector for solid engineering reasons.
A protector adjacent to your computer only claims to protect from surges that typically cause no damage. Your concern is another type of surge that typically causes damage. It must be eliminated where utility wires enter. Cable needs no such protector. Better protection provided only by a wire. But AC electric must be earthed by a 'whole house' protector. Earthed to the same ground used by cable to protect that computer. And everything else you own.
Any sacrificial device does not do protection, is grossly undersized, is often obscenely overpriced, and is recommended by hearsay and advertising. One need only learn how electricity works to understand that a failed protector left a surge fully connected to the computer. Adjacent protectors have no number and need no number. A profit center need only make subjective claims to sell for tens or 100 times more money - because it easily fails.
BTW, they might mention the homeowner is responsible for and maintaining the most important component that protects your computer, TV, etc. You may want to learn this rather than spending tens or 100 times more money on a device that does not even claim that protection.
