Approved antennas in Europe/CE
The gain of the antenna connected to the main antenna port, minus the antenna
cable loss, must be less than 4 dB to stay below the 100-mW EIRP transmit
power limit.
The AUX port is only used to receive; it never transmits. So, high-gain antennas
such as 19 dB can be attached to this port for receive diversity.
NOTE: In France, the user is responsible for ensuring that the selected
frequency channels comply with French regulatory standards. At the time of
this printing, only channels 10 through 13 can be used in France.
Approved antennas in Mexico
The gain of the antenna connected to the main antenna port, minus the antenna
cable loss, must be less than 12 dB to stay below the 650-mW EIRP transmit
power limit.
