One discussion in a ham radio group:

The basic scenario is to install a Single Point Ground System
that is installed at the building entry. It shunts everything
to ground before it goes in the building. If you can keep it
outside, then you don't really have to do much inside. IMO
disconnecting the cables is more psychological than preventive.

Another's experience:

Well I assert, from personal and broadcast experience spanning
30 years, that you can design a system that will handle
*direct lightning strikes* on a routine basis. It takes
some planning and careful layout, but it's not hard, nor is
it overly expensive. At WXIA-TV, my other job, we take direct
lightning strikes nearly every time there's a thunderstorm.
Our downtime from such strikes is almost non-existant. The
last time we went down from a strike, it was due to a strike
on the power company's lines knocking *them* out, ...
Since my disasterous strike, I've been campaigning vigorously
to educate amateurs that you *can* avoid damage from direct
strikes. The belief that there's no protection from direct
strike damage is *myth*. ...
The keys to effective lightning protection are surprisingly
simple, and surprisingly less than obvious. Of course you
*must* have a single point ground system that eliminates all
ground loops. And you must present a low *impedance* path for
the energy to go. That's most generally a low *inductance*
path rather than just a low ohm DC path.

Lastly, what many consider a benchmark in the art of earthing:

Good on you for at least knowing you should ground it. There
are countless resources on the web with this info, a simple
