11 Antennas

11.1 Internal Antennas

Ranger V4.4 contains cellular, Wi-Fi, Bluetooth, and GPS antennas.

Cellular, Wi-Fi, and Bluetooth antennas are capable of radiating RF energy. Ranger units should be installed and

operated with a minimum distance of 20 cm (8”) between the radiator and the operator or any passengers.

The orientation and mounting location of Ranger V4.4 can have an effect on unit performance. To optimize GPS

performance, mount the Ranger vertically with a clear view of the sky.

11.2 External Antennas

If desired, an external GPS antenna can be used with Ranger V4.4.

Specific antenna selection depends on the individual system setup. Contact your Customer Care representative

for assistance in selecting an appropriate antenna.

Some important features to consider are:

• Compact construction

• Durability

• Weatherproofing

• Temperature stability

• Mode of Installation

• Compatibility with NAVSTAR and GLONASS systems

• QMA Plug to be compatible with Ranger V4.4

Ground plane style antennas are ideally mounted on the center of a metal vehicle roof. Glass mount antennas

should be mounted away from metal objects.

When using an adhesive antenna, it is extremely important to make sure that the surface of the mounting

location has been thoroughly cleaned. Use isopropyl alcohol to clean the surface just before securing the adhesive

pad.

11.3 Cable Routing

The bend radius of the antenna coaxial cable depends on the type used. Apply bend radius per the antenna

manufacturer's recommendations.

Avoid routing the antenna cable in parallel with the vehicle wiring over long distances.

11.3.1 Connectors

• QMA - The QMA connector is used for GPS and is a snap-on version of the SMA connector.

Do not coil excess antenna cable slack.
