On another group, I heard about a lightning strike to a house, via the TV
aerial. Aerial went to a DA. Seemed it burnt out all the house wiring and
every appliance in it. Requiring the owners to move out for months while
it was all sorted. Seems it also travelled to other houses in the street
too via the mains and caused much damage there too. Was rather surprised
to read this. I've seen a TV destroyed - but not so much extra damage.

I doubt if a strike to a tv aerial would travel outside the preises struck.
More likely an overhead line was struck and got into other houses that way.
