Drilling of threaded holes and cable breakthrough
1. Clear the area where the
antenna is mounted from
paint, corrosion or any
anodized layer.
2. Clear this area from any
dust, brake dust, cutting
chip, oil or fat.
Preparation of roof
Use parts of the packaging to
easily position the antenna above
the cable breakthrough as
indicated on the picture.
Feed all cables through the hole.

1)
For a minimum 8mm thick contact surface, use screws with a
minimum length of 18mm.
For a minimum 12mm thick contact surface, use screws with a
minimum length of 22mm.
2)
Use mounting screws according to ISO 4762.
Screws are not included.
Mounting
Connect the cables. Hold the pigtail connectors
during cable attachment. Avoid all tension,
torsion and bending forces.
GNSS connector (if present):
GNSS without LNA (check product datasheet):
Do not apply a voltage as this antenna is DC
grounded.
GNSS with LNA (check product datasheet):
Take ESD precautions.
Inner conductor: 3…5 V
Outer conductor: GND
Place sealing gaskets in the circled slots in the outer
contact surfaces.
Remove the packaging parts and lower the antenna
towards the roof.
Avoid moving the antenna once it touches the mounting
surface.
