The modem antennas work with the AER, ARC, and COR models that include an integrated modem. Some antennas may not be optimized for all frequency bands for a particular model (see individual antenna specifications). In some cases, a single antenna connected to the main (primary) antenna port will provide sufficient gain. To see “true” 4G speeds on LTE, or better performance, use two external antennas. For example, two antennas may provide 15 Mbps throughput and one antenna may only provide 8 Mbps throughput.
In most cases, a single antenna connected to the main antenna port will provide sufficient gain. To get “full” 4G speeds on LTE, or for enhanced performance on any modem, you may use two external antennas. Take extra care while attaching the cable to the modem. Be careful not to over-torque the SMA connector on the modem. Finger tight is sufficient (the maximum torque is 7kgf-cm). If you are using a single antenna, you may want to turn off the auxiliary antenna port. Log into the administration pages and go to Internet Connection Manager.
