User manuals for transmitters equipped with
detachable antennas shall also contain the following
notice in a conspicuous location.
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 for the
MRF24J40MC module are listed in Table 3-2.

This radio transmitter (identify the device by
certification 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.
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.
