RF EXPOSURE WARNING
To comply with FCC and Industry Canada regulations limiting both maximum RF output
and human exposure to RF radiation, maximum antenna gain must not exceed:
Cellular (800MHz) band < 4 dBi
PCS (1900MHz) band < 3.5 dBi
AWS (1700MHz) band < 3.5 dBi
To comply with the CE regulations, maximum antenna gain must not exceed the antenna
gain of the Taoglas TG.09.0113 antenna.
Diversity WWAN Antenna
The diversity antenna is labelled WWAN Div GPS on the front panel.
recommendations.
IMPORTANT: The diversity antenna is by default disabled (from firmware version 1.9.0 onwards).
Learn how to enable the diversity
Connectors
Uses the same type of connector as the main WWAN antenna
Frequency range
Receive diversity only works on WCDMA and CDMA bands
Only WCDMA and CDMA bands have to be supported by the diversity antenna.
The GPS frequency must also be supported if GPS functionality is desired on the gateway.
Efficiency
Radiation pattern: Omni-directional
Efficiency over all used frequencies: > 25%
Maximum VSWR: < 2.5:1 with 50 ohm reference impedance
Polarization
Linear
Mutual coupling
(main antenna and diversity antenna)
Isolation: > 8dB
Envelope correlation coefficient: < 0.5
GPS Antenna
The gateway only supports passive GPS antennas. There is no power supply for active antennas on the
RF connector. For accurate GPS operation make sure the GPS antenna has a clear view of the sky.
