2.1.3 FCC Approved Antennas
The RF Engine modules are FCC-approved for fixed base station and mobile
applications on channels 11 thru 26 of the ISM 2.4GHz frequency band as
defined in I.E.E.E 802.15.4 specifications. The FCC requirement for mobile
applications states that the antenna must be mounted at least 20 cm (8 in) from
nearby persons.
Notice: To reduce potential radio interference to other users, the antenna type
and its gain should be chosen so that the equivalent isotropically radiated power
(e.i.r.p) is not more than that permitted for successful communication. This
module has been designed to operate with the antennas listed below in Table 2.1,
and having a maximum gain of 5 dB. Antennas not included in this list or having
a gain greater than 5 dB are strictly prohibited for use with this device. The
required antenna impedance is 50 ohms.

AC12001 Dipole (half-wave RPSMA) 5.0dBi Fixed/Mobile 20 cm.
AC12002 Dipole (quarter-wave RPSMA) 4.9cBi Fixed/Mobile 20 cm.
AC12003 Dipole (quarter-wave RPSMA) 2.0dBi Fixed/Mobile 20 cm.
RF Exposure
Warning: This equipment complies with FCC radiation exposure limits
set forth for an uncontrolled environment. This equipment should be
installed and operated with minimum distance 20cm between the radiator
and your body. This transmitter must not be co-located or operating in
conjunction with any other antenna or transmitter.
Notice: The preceding statement must be included as a CAUTION statement in
OEM product manuals in order to alert users of FCC RF Exposure compliance.
