FCC-approved antennas (2.4 GHz)
The XBee 3 RF Module can be installed using antennas and cables constructed with non-standard
connectors (RPSMA, RPTNC, etc.) An adapter cable may be necessary to attach the XBee connector to
the antenna connector.
The modules are FCC approved for fixed base station and mobile applications for the channels
indicated in the tables below. If the antenna is mounted at least 20 cm (7.87 in) from nearby persons,
the application is considered a mobile application. Antennas not listed in the table must be tested to
comply with FCC Section 15.203 (Unique Antenna Connectors) and Section 15.247 (Emissions).
The antennas in the tables below have been approved for use with this module. Cable loss is required
when using gain antennas as shown in the tables.
Digi does not carry all of these antenna variants. Contact Digi Sales for available antennas.
1. If using the RF module in a portable application (for example, if the module is used in a hand-
held device and the antenna is less than 20 cm from the human body when the device is in
operation), The integrator is responsible for passing additional Specific Absorption Rate (SAR)
testing based on FCC rules 2.1091 and FCC Guidelines for Human Exposure to Radio Frequency
Electromagnetic Fields, OET Bulletin and Supplement C. The testing results will be submitted
to the FCC for approval prior to selling the integrated unit. The required SAR testing measures
emissions from the module and how they affect the person.
