MOUNTING INSTRUCTIONS
2
Choosing a mounting position
When choosing a mounting location try to ensure that the whole antenna, in particular the whip section is as high and as far
away as possible from metallic obstructions (e.g. roof racks, or vehicle pillars). When mounted in a vertical position well
removed from such obstructions the antenna will provide optimum performance.
Installation Procedure
1.
Fit the CD90 base and cable assembly to the mounting bracket to be used.
2.
Fit the hex locknut on the lower surface of the mounting bracket and tighten the assembly into place.
4.
Fit the mounting bracket to the vehicle. The preferred position for gutter mounts is near the centre door pillar on the
drivers side.
5.
Route the coaxial cable into the vehicle and to the transceiver via the best and most direct path.
NOTE: Where the cable enters the vehicle try to avoid positions which will result in excessive wear or compression.
It is a good idea when using gutter mounts to use the rear door rather than the front door for example.
6.
Fit the coil and whip section to the CD90 base.
7.
Fit the connector (not supplied) to the coaxial cable and connect to the transceiver.
8.
Test the VSWR using an in-line RF power meter.
9.
Do not tune the antenna. This antenna is pre-tuned and should not require adjustment. If the VSWR is in excess of
1.5:1, test the coaxial connectors and cables.
There should not be a short between the outer and centre conductors
of the coxial cable. If there is a short across the coaxial cable, this would indicate incorrect coaxial connector fitting.
Please seek your dealer’s advice.
