Yaesu G-1000DXC Mode D'emploi page 16

The installation of a rotatable antenna on a tower system
is a dangerous and potentially life-threatening task, if
due care is not taken.
A tower must never be installed in a position where it
could fall across power distribution cables in the event
of a catastrophic tower failure during a windstorm or
earthquake.

Important !
The control cable attached to this rotator could, in the
event of a nearby or direct lightning strike, carry lethal
voltages down the cable and into your home. Yaesu
strongly recommends the installation of suitable light-
ning arrestors on all control cables and coaxial lead-in
cables from your antenna installation. See your dealer
for details of available lightning-protection devices.
