Can I install an external antenna on the OBU?

The OBU communicates with satellites (GNSS) and mobile networks (GSM) using internal antennas to send or receive signals. It is possible to install an external antenna on the OBU to improve the communication quality and/or to reduce exposure to electromagnetic fields.

Satellic does not offer any external antenna. You may buy it at your preferred supplier and get it installed by the workshop of your choice. The external antenna must be connected to the GSM connector (on the back of the OBU) with a FMA female connector and to the GPS/GNSS connector with a SMA male connector. The GSM-antenna should support 900 and 1800 Mhz cellular communication (bi-band).

The following document illustrates how to connect the antenna to your OBU.
