    Indeed. And why you should at least have some protection on anything signal or power coming in from the outside if you are not in a city, even if it is a run between two buildings. A lightning strike in a tree nearby can easily induce really nice transients on even short runs of cable.

      It seems that the grouding on the nearby house was OK.
      No marjor damages there (just one digital TV tuner box and light bulb damaged).

      It was good that electricity, cable TV and telephone linews were put underground just few years ago.
