CN3100 Vehicle Modem - Installation Guide - G7609 - 3.0
- DRAFT
The CN3100 has four antenna connectors — two Tx/Rx and two Rx-only.
All connectors are always used.
The WiFi antenna can be positioned in any convenient location.
On a vehicle, magnetic-mount or through-hole mount antennas may be used.
FOR OPTIMUM PERFORMANCE
The CN3100 should be placed as close as possible to the antennas.
The antenna cable lengths should be as short as possible.
Use of Low-loss cables (LMR 195/240 or equivalent) is highly recommended.
When using four antennas
The cables from the two Tx/Rx connectors on the CN3100
should be connected to the two antennas on one diagonal.
The cables from the two Rx connectors on the CN3100
should be connected to the two antennas on the opposite diagonal.
When using two dual-polarity antennas, connect the cables as shown:
