Installation Guide

3. Prepare and Drill Hole
4. Fitting the Antenna
Mask the panel area around the hole position to protect the paintwork and headliner. Drill a pilot hole,
and then either use a hole cutter of correct size or increase the hole diameter to 19mm (3/4”), ensuring
that drill/cutter bit does not contact the internal headliner. Clean area around the hole, carefully removing
all swarf. Apply some petroleum jelly or paint around the hole to prevent corrosion.
Note: The adhesive pad provides a means to fixture the antenna and to prevent rotation during
installation it alos augments the sealing function of the antenna to mounting panel provided by the
sealing boot. The temperature range for optimum pad bonding process is 21°C (70°F) to 37°C (100°F)
- it is recommended that the installation is not carried out in temperatures of less than 50°F (10°C).
Remove the protective backing from the underside of the antenna and feed the coaxial cables through
the panel. Position the antenna over the hole ensuring correct orientation and stick the antenna to the
panel by applying firm downward pressure.

5. Routing and Terminating Coaxial Cable(s)
Caution – A slotted/split nut is provided in order to simplify fitting it over the coaxial cables. When fitting
the nut, it is important to ensure that the cables are held centrally whilst the nut is correctly started on
the threads.
The nut should fit freely by hand and only require a final tighten by spanner.
Assemble the nut and washer from underside and tighten to recommended torque of 5Nm (3.6 ft/lbs).
Ensure that the sealing boot is properly compressed.
Connect the extension coaxial cables to the antenna and route the cables to the radio equipment.
Fit the correct coaxial connectors or adapters to the cables as required.
When routing the cables take care to avoid running them adjacent to any
existing vehicle wiring or fouling any moving vehicle components. The cables
must not be routed in front of any airbag device.
