HI,

Good to read : http://www.astrosurf.org/lombry/qsl-...protection.htm

Personnaly, in my humble opinion, under thundery weather there is no better
solution than unpluging all electronic devices...

Thierry, ON4SKY

Agree! But, I still lost an ICOM 756 Pro II when disconnected from
antenna,
and had the power supply unplugged. A ground loop in the external ground on
the 756 and the power supply, where 12 volt return is tied to chassis,
caused
damage to the power connector on the 756 and fried the 756 internal
cabling and
circuit boards were carbonized.

I'm still waiting for my insurance settlement.

For sure, as soon as there is a sink, a path of lower resistance, the
lightning will find it and will follow it to your most expensive accessory..
This canal can be the coaxial, the house cabling system, even yourself if by
mistake you touch a metallic device during the thunder. Even the ground as
state in my article can be an excellent way for the lightning to strike your
installation. Hence it is better to entrust this installation to experts.

So I when I say to unplug all devices, this is *all* cabling system,
including grouding.

Usually the insurance do an excellent job and you should be able to rebuy
all your defective devices.

Good luck.
