The antenna mast must be structurally secure. Check how secure the various attach-
ments are.
The antenna mast must be within reach of the cable. Ideally, the antenna cable should
be protected outside (from frost, sun, unauthorised and mechanical influences etc.).
In particular, make sure the antenna mast has sufficient load capacity. If you are mount-
ing the mast on the roof, make sure the roof is fully sealed again afterwards.
Lightning protection
The antenna mast should be positioned near a lightning conductor. A suitable lightning
conductor must be installed where necessary.
The outdoor antenna is not designed to be struck directly by lightning and must be pro-
tected accordingly. The antenna must therefore be mounted in areas that are protected
against lightning (Lightning Protection Zone 0B). The corresponding separation dis-
tance (IEC 62305) must be complied with.
Earthing and lightning protection work may only be carried out by electricians specifi-
cally qualified for such work.
The appropriate earthing clamps must be used to create an equipotential bonding
between a cable shield and an equipotential bonding bar that complies with regula-
tions.

Antenna cable and antenna connection:
It must be possible to connect the outdoor antenna to the Gigaset SX685 WiMAX by
means of an antenna cable.
Please note that the antenna connection must be protected from the impact of rain and
other weather effects.
Use cable clamps to attach the cable to the mast. Please note that the cable must be
long enough to turn the antenna at a later stage.
Antenna alignment:
When aligning the antenna, we recommend asking a second person to run the basic
setup wizard on the PC and to check the reception quality on the screen; see Chapter
"Making the basic settings" on page 25.
After installation:
Tighten all screw connections to the torques listed in the installation instructions.
Secure the antenna cable with cable clamps and cable ties. The cable must be protected
from exposure to pressure and tension.
