6 Antenna Installation
Antenna location has an extremely significant impact on the performance of a wireless
modem. Mentor Engineering recommends using a roof top antenna installed in the center
of the vehicle roof for best coverage and to meet SAR/MPE radiation specifications (See
Following section: RF Radiation Specifications).
Antenna installation requirements vary between different antennas. Contact Mentor for
specific Antenna information for your application. The following Figure shows the
preferred location of a rooftop antenna.

6.1 General Antenna Guidelines
• Position the antenna as high as possible on the body of the vehicle.
• Keep the RF cable as short as possible. Cut the excess cable during an
installation. Do not wrap it up. Excess cable adds unnecessary loss to the
signal.
• Ensure the antenna is in a vertical position during operation.
• Use proper RF connectors. Use a straight SMA connector when using a
MultiConnect. (Refer to the SMA Connector Assembly documentation
provided)
