If a magnetic mounted antenna is used, take care to locate the magnetic base
in a location which avoids interference to the compass mechanism, since
magnets may affect the accuracy or operation of the compass. If metallic panels
are used, do not block the reception paths for installed antennas such as Global
Position Satellite Receivers, if so equipped.
For an optimum performance of antennas, consider these aspects:
 The antennas should have an unobstructed view of the sky,
especially for GNSS receivers. The antennas should not be shielded by
any metal object or other impenetrable material.
 The antennas have to be safe from damage during normal
vehicle operation and maintenance.
 GNSS antenna should not be shielded from satellite signals by
metal objects or other impenetrable materials.
 Separate GSM and GNSS antenna at least 50 cm.
 Choose a location with access both above and below the
antenna-mounting surface. This access is required for installing
fasteners and for routing the antenna cable.
 Keep the antenna as separate as possible from the microphone
and loudspeaker when hands-free option is used.
11.2.2 Antenna Tuning
It is important that the antenna is properly tuned and Voltage Standing Wave
Ratio (VSWR) less than 2.0:1, and to avoid RF current on the antenna cable
shield.
11.2.3 Antenna Cable Routing
Always use a high quality, one-piece coaxial cable. Connector quality and
termination techniques are quite important.
The antenna cables should be treated in the same way as the control and
power cables. Avoid sharp edges and pinches and keep the cable as short as
possible. Also avoid routing the antenna cable in parallel with other control or
power wiring over long distances. If it is necessary to cross over wiring, cross at
right angles.

To connect owa4x cables follow these instructions:
• Allow enough cabling to enable the removal of the equipment.
• Ensure cables are not corrupted or rubbing against sharp objects.

Choose a location for owa4x which allows for convenient routing and
connection of the antenna and interface cables, and which has access to power
source and status LEDs. When selecting a mounting location, avoid the
following hazards:
 Direct exposure to weather.
 Excessive heat or cold.
 Excessive humidity.
 High vibration areas.
 Corrosive fluids and gases.
