Transmitter Antenna (from Section 7.1.2 RSS-Gen,
Issue 3, December 2010): User manuals for transmit-
ters shall display the following notice in a conspicuous
location:
Under Industry Canada regulations, this radio
transmitter may only operate using an antenna of a
type and maximum (or lesser) gain approved for the
transmitter by Industry Canada. To reduce potential
radio interference to other users, the antenna type
and its gain should be so chosen that the equivalent
isotropically radiated power (e.i.r.p.) is not more than
that necessary for successful communication.
Conformément à la réglementation d'Industrie
Canada, le présent émetteur radio peut fonctionner
avec une antenne d'un type et d'un gain maximal (ou
inférieur) approuvé pour l'émetteur par Industrie
Canada. Dans le but de réduire les risques de
brouillage radioélectrique à l'intention des autres
utilisateurs, il faut choisir le type d'antenne et son
gain de sorte que la puissance isotrope rayonnée
équivalente (p.i.r.e.) ne dépasse pas l'intensité
nécessaire à l'établissement d'une communication
satisfaisante.
The above notice may be affixed to the device instead
of displayed in the user manual.
User manuals for transmitters equipped with detach-
able antennas shall also contain the following notice in
a conspicuous location.
This radio transmitter (identify the device by certifi-
cation number, or model number if Category II) has
been approved by Industry Canada to operate with
the antenna types listed below with the maximum
permissible gain and required antenna impedance
for each antenna type indicated. Antenna types not
included in this list, having a gain greater than the
maximum gain indicated for that type, are strictly
prohibited for use with this device.

à l'établissement d'une communication satisfais-
ante.
Immediately following the above notice, the
manufacturer shall provide a list of all antenna types
approved for use with the transmitter, indicating the
maximum permissible antenna gain (in dBi) and
required impedance for each.

APPROVED EXTERNAL ANTENNA
TYPES
Transmitter Antenna (from Section 7.1.2 RSS-Gen,
Issue 3, December 2010):
The MRF24J40MD/ME module can only be sold or
operated with antennas with which it was approved.
Transmitter may be approved with multiple antenna
types. An antenna type comprises antennas having
similar in-band and out-of-band radiation patterns.
Testing shall be performed using the highest gain
antenna of each combination of transmitter and
antenna type for which approval is being sought, with
the transmitter output power set at the maximum level.
Any antenna of the same type having equal or lesser
gain as an antenna that had been successfully tested
with the transmitter, will also be considered approved
with the transmitter, and may be used and marketed
with the transmitter.
When a measurement at the antenna connector is
used to determine RF output power, the effective gain
of the device's antenna shall be stated, based on mea-
surement or on data from the antenna manufacturer.
For transmitters of output power greater than 10 milli-
watts, the total antenna gain shall be added to the mea-
sured RF output power to demonstrate compliance to
the specified radiated power limits.
Testing of the MRF24J40MD/ME module was per-
formed with the antenna types listed in Table 2-1
Tested External Antenna Types
