Note
CANADA ONLY: This device has been designed to operate with the antennas listed in
having a maximum gain of 12dBi. Antennas not included in this list or having a gain greater than 12dBi are
strictly prohibited for use with this device. The required antenna impedance is 50 ohms.
Note
To reduce potential radio interference to other users, the antenna type and its gain should be so chosen
that the Effective Isotropic Radiated Power (EIRP) is not more than that permitted for successful
communication.
