2.2 GPS Antenna Installation
Prepare the GPS
antenna To prepare the GPS (Red) antenna for mounting on the vehicle’s roof, carry out the
following steps:
1. Clean the vehicle cab’s roof with Windex
®
glass cleaner or a similar product, to
prepare it for the installation of the antenna.

Start all antenna cable connections by hand before using the supplied
spanner to tighten. Do not over tighten the cable connectors. Run the
threads to the end by hand, and tighten only 1/8th turn more with the
spanner.
2. Take the Twin RF Cable and connect the small connector to the GPS antenna
(shown at location 2 in the picture above).
3. The other metal connector of the Twin RF Cable is for the whip antenna. Remove
the outer nut and washer from the connector. Insert the thread of the connector
as shown at location 3 and in the exploded view in the picture above, so the
thread is accessible from the top of the GPS antenna. Attach the washer and fix
with the nut.
4. Run the cables through the circular slot provided on the bottom side of the cover.
Align each cable with the slot and push it into the slot using the antenna cable
grommets and antenna cable supports provided.
5. You have several options for how you want the cables to exit the antenna cover.
Choose the option that works best for your application.
6. Install the whip antenna on the GPS
antenna by screwing it onto the
connector installed in Step 3
above.

The whip antenna should be
mounted on the GPS antenna
so it will fold backwards if
needed when the GPS
antenna is mounted on the
vehicle.
