Main Page > FAQ > Other Topics > Mobile Main and AUX AntennasIn Teltonika devices, one mobile antenna connector is "MAIN" (used for all data communication, including transmitting and receiving the data), while the another one is "AUX" (used only for receiving).
Depending on what technology (3G/4G) is used to connect to the mobile network provider, "AUX" antenna performs a different role:
- When "3G" technology is used, "AUX" antenna is used as "diversity antenna" for error correction. Its effects are mostly noticeable in poor mobile signal strength areas.
- When "4G (LTE)" technology is used, "AUX" antenna is used as a secondary receiving antenna, increasing overall mobile download speed of the device.
We recommend you to always have both mobile antennas connected for the best performance. However, if the situation does not allow you to use both mobile antennas (e.g. if the router is mounted in tight space where there is only enough space for one antenna), then "MAIN" mobile antenna connector should be used.
