5.1.4 Installing the Cable Gland and Mounting Plate
Tip
If you have previously used a Kathrein HDM 140/141 jointed tripod mast or another mast with a diameter of
34 mm, you can continue using the existing through hole in the roof.

1. In the centre of the intended position of the turntable, drill the opening for the cable gland with a circular cutter of
Ø 38 mm .
2. Deburr the hole with a round file or emery paper.
3. Provisionally insert the roof duct into the drilled hole (Fig. A).
4. Place the mounting plate on the roof of the vehicle such that the centre hole is positioned centrally to the cable gland.

of the vehicle (Fig. B).
5. Mark the positions of the six fastening holes on the vehicle roof in a pitch circle.
Tip
The size of the holes and the choice of fastening screws to be used (not included in the scope of delivery)
depend on the type and thickness of the materials used in the roof structure. If the roof panelling (plastic
roofs) is sufficiently strong, it is recommended to always use round head screws, plain washers and self-
locking nuts to secure the glued mounting plate.
6. If the roof panel material is very thin and does not provide adequate holding power within the insulation material,
make through holes of Ø 5.5 mm into the interior of the vehicle and use galvanised M5 round head screws of suffi-
cient length.
Make sure that you use a sufficiently strong support that can withstand the bolt tensile forces (large plain washer or a
complete reinforcing plate).
