which leaves me wondering about the big lightning rod 5m above my roof,
and the coaxial cable connecting it to the DVB card in my mail and
file-server.  I put a lightning arrestor(?) in the cable in the roof, a
small cylindar maybe 3x8cm. Any use?

Would I be right in guessing that the telephone system is good at
collecting surges from lightning strikes over a large area, while the TV
antenna will only collect very near strikes, so is less likely to do
damage? (But when it does...)
