I have a plate with jacks (that are all grounded) for my antennas and cables that has a bunch of jacks on it so I can just screw the cables onto the plate.
The problem is, and has been, not doing it, or not being here to do it.
But even when I did do it, it still can happen.
When I lost my UPS, not too long ago, it came in through the phone line, blew up the UPS, but the PC connected to the UPS just lost the modem, and still worked fine otherwise.
