Refer to the picture in section 5.5 showing the positions of the connectors for the external antennas.

6.5.7 GNSS antenna connection

For best results when the unit cannot be mounted with a good view of the sky, the external GNSS antenna

should be used. Mount the GNSS antenna horizontally where the least metal (or any conductive) obstruction

between the antenna and the satellites will occur. The top side of the antenna is the rounded side. For best

results place the antenna on a metal surface facing towards the sky (see picture below). Mount as far

away from any radio signal or wire bundles as possible.

a) Avoid pinching the coaxial cable or bending it sharply (zigzags).

b) It would be better to circle/coil excess wires. Take care not to tie coax wires too tight. Using the

broadest possible cable tie (refer to section 6.4).

c) The best place to circle/coil the wires is about 300 mm in line from the antenna.

6.5.8 GSM antenna (internal)

The standard product only has an internal Modem antenna.

7 Positioning the MiX 4000 Unit in the vehicle

Note: Please follow the instructions, regarding the positioning of product components, as contained in the

“Safety” section, of this document.

 The MiX 4000 must be installed inside the passenger compartment or the driver cabin, to protect it from

possible damage by water, solvents, fuel or other environmental factors.

 The MiX 4000 should not be installed in or near the ventilation, heating system, or hot surfaces, which

may cause it to overheat or be damaged by condensed water vapour. Also, do not install together with

other electronic equipment in an enclosed box that would trap the heat and cause the temperature to rise

 The MiX 4000 should be installed in a position where it will not be subjected to pressure, impact or

excessive vibration. Uneven surfaces, where the box can be deformed or damaged should be avoided.

 Select the installation position carefully before proceeding with the installation.

 Mark and drill the required holes.

 Route cables from the unit to the appropriate senders within the vehicle. Additional information can be

found in the “Harness Installation” section (6.5 of this document).

The Unit contains an internal Modem antenna and must be mounted more than 20cm away

from the human body under normal operating conditions.
