Installation 29
WWAN Antenna Connection
Connect the cable connector (Mini UHF) of the vehicle RF antenna, if an internal Wireless
Wide Area Network (WWAN) radio is used.
Important Note: Always connect the W-WAN antenna to the MAIN connector at the
back panel of the CPU box. If two W-WAN antennas are used, connect the antennas to the
MAIN and AUX connectors.
Installation Guidelines
Vehicle antennas must be installed external to the vehicle and in accordance with:
• The requirements of the antenna manufacturer/supplier.
• Instructions in the installation manual of the external radio (in case an external radio is
used)
.
IMPORTANT NOTE: T
o
assure optimum performance and compliance with RF Energy
Safety standards, these antenna installation guidelines and instructions are limited to metal-
body vehicles with appropriate ground planes and take into account the potential exposure of
back seat passengers and bystanders outside the vehicle.
For detailed product safety and RF exposure, refer to Safety and General Information leaflet,

Selecting an Antenna Site/Location on a Metal Body Vehicle
1. External installation – Check the requirements of the antenna supplier and install the
vehicle antenna external to a metal body vehicle in accordance with those requirements.
2. Roof top – For optimum performance and compliance with RF Energy Safety standards,
mount t
he antenna in the center area of the roof.
3. Ensure that the installation surface is grounded by connecting grounding straps between
th
e surface and the vehicle chassis.
4. Ensure that the antenna cable can be easily routed to the MW810. Route the antenna
ca
ble as far away as possible from any vehicle electronic control units and associated
wiring.
5. Check the antenna location for any electrical interference.
Recommended antenna: PCTEL MLPVDB800/1900S Compact Size Multiple Band Low
Prof
ile Vertical Antenna.
To comply with safety regulations, the distance between antennas
and people sitting inside the vehicle must be more than 8 inches
(20 cm).
When mounting antennas, the distance between the antennas
must
be more than 8 inches (20 cm).
Any two metal pieces rubbing against each other (such as seat
spr
ings, shift levers, trunk and hood lids, exhaust pipes, etc.) in close
proximity to the antenna can cause severe receiver interference.
