The length of the antenna cable may affect the signal strength. Choose the appropriate cable type and length. The
table below provides can help pre-determine the loss to expect.
Per FCC requirements the antenna gain including cable loss must not exceed 7.5 dBi in the Cellular band, 3 dBi in
the PCS band, 5.5 dBi for LTE Band 4, and 9 dBi in the LTE Band 17 for RF exposure purposes of 2.1091. The
antenna(s) used for this transmitter must be installed to provide a separation distance of at least 20 cm from all
persons. The antenna(s) used for this transmitter must not be co-located or operating in conjunction with any
other antenna or transmitter except in accordance with FCC multi-transmitter evaluation procedures.
Installation and Verification
When installing the antenna, follow the FCC and Industry Canada guidelines and keep the following in mind:
•
Mount the antenna(s) at least 30 cm (12 inches) from other antennas
•
Do not install the antenna in a closed metallic enclosure (such as a cabinet or the trunk of a car).
Once a modem has a signal, the Signal LED indicator will start flashing according to the signal strength. Addition-
ally, the Web Interface can display the received signal strength (RSSI) on the status page. The modem should have
at the very least one bar of signal strength.
