Allowed Antennas to be used with the Radio Module
The Integrator must request from Atheros sales or regulatory contact person the current list of allowable
antennas for use with the specific radio module. This information is not available on the public FCC database
but will be provided by Atheros. Atheros will provide a table of antenna type(s) models, cable lengths, and
peak gain in each band.
Generally, the list will include Omni-directional Inverted-F (PIFA) and stamped metal/film antennas for use
inside laptops. In some cases, dipole antenna types may be included in the available list. Peak gain including
cable losses are quoted in the table provided by Atheros.
Use of any of the antennas in the list (identical or equivalent antenna with lower gain, dimensions and cable
lengths) is acceptable in the host device, without any further FCC testing or submission.
However, use of an antenna that is higher gain than those on the list or is a Different Type, requires additional
testing and submission to the FCC. Therefore, antennas with higher gain or different type than specified by
Atheros may not be used with the Atheros module until new testing and reporting is completed.
You must contact the Atheros Regulatory Group to report any higher gain or new antenna type to be used with
the module.
Antenna Placement
This 1x1 802 11 b/g/n module has been certified by FCC as single module approval with the
following restrictions:
• The most conservative antenna-to-user separation distance shall be greater than 0.6 cm
to end user or near-by person. 0.6 cm physical separation distance is measured by
positioning the display section of notebook/Netbook/Laptop computers perpendicular
to the keyboard section. Measure the distance from the nearest point of antenna to the
bottom of host.
• Consult with Atheros to determine the allowable rotational orientations for vertical and
horizontal antenna installation in applicable host devices.
