FCC-approved antennas
The equipment can be installed using antennas and cables constructed with non-standard connectors
(RPSMA, RPTNC, and so forth) 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 25 cm from nearby persons, the
application is considered a mobile application.
The antennas below have been approved for use with this module. Digi does not carry all of these
antenna variants. Contact Digi Sales for available antennas.
