Information about the optional outdoor antenna
The best results will be obtained if the outdoor
Fig. 1
antenna is in sight of the WiMAX base station (cf.
Fig. 1).
If a line of sight is not possible, you can reflect the
radio waves off neighbouring buildings. To do
this, direct the antenna at the building it is to
reflect off and not at the base station (cf. Fig. 2).

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.
