FCC-approved antennas (2.4 GHz)
XBee / XBee-PRO RF Modules 802.15.4 Product Manual 99
• For XBee modules where the antenna gain is less than 13.8 dBi, no additional SAR testing is
required. The 20 cm separation distance is not required for antenna gain less than 13.8 dBi.
• For XBee modules where the antenna gain is greater than 13.8 dBi and for all XBee-PRO modules,
the device must undergo SAR testing.
This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation. This equipment generates, uses and can
radiate radio frequency energy and, if not installed and used in accordance with the instructions, may
cause harmful interference to radio communications. However, there is no guarantee that
interference will not occur in a particular installation.
If this equipment does cause harmful interference to radio or television reception, which can be
determined by turning the equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures: Re-orient or relocate the receiving antenna,
Increase the separation between the equipment and receiver, Connect equipment and receiver to
outlets on different circuits, or Consult the dealer or an experienced radio/TV technician for help.
FCC-approved antennas (2.4 GHz)
XBee/XBee-PRO RF Modules can be installed using antennas and cables constructed with standard
connectors (Type-N, SMA, TNC, etc.) if the installation is performed professionally and according to
FCC guidelines. For installations not performed by a professional, non-standard connectors (RPSMA,
RPTNC, etc) must be used.
The modules are FCC-approved for fixed base station and mobile applications on channels 0x0B -
0x1A (XBee) and 0x0C - 0x17 (XBee-PRO). If the antenna is mounted at least 20cm (8 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).
XBee RF Modules (1 mW): XBee Modules have been tested and approved for use with the antennas
listed in the first and second tables below (cable loss is required as shown).
XBee-PRO RF Modules (60 mW): XBee-PRO Modules have been tested and approved for use with
the antennas listed in the first and third tables below (cable loss is required as shown).
The antennas in the tables below have been approved for use with this module. Digi does not carry
all of these antenna variants. Contact Digi Sales for available antennas.
