Your FX4100 5G Cellular Router is equipped with four internal antennas. In addition, the device has two external full spectrum cell SMA ports (0.6-6 GHz each) to support two external antennas.

NOTE: The FX4100 integrated internal antennas provide an average 4 dBi peak gain across all frequency ranges. If you are getting 4-5 bars signal strength, external antennas are not necessary and will not add to performance. In fact, adding the wrong external antennas (less than 4 dBi, including cable loss) will decrease your router’s performance. Situations where external antennas are needed are rare. Contact your Account team for more information about external antennas.

To use external antennas:

1. Remove the SIM/EXTERNAL ANTENNAS cover on the back of the router.

2. Finger tighten your external antennas to the CELL1 and CELL2 external antenna ports.

3. Set the switch to EXT.ANT.ON. When enabled, each external port supports the full cellular frequency range of 0.6-6 GHz. Two of the internal antennas are disabled. The other two internal antennas remain active. An antenna icon appears on the main screen of the device display.

NOTE: Contact your Account team for more information about external antennas.
