This device has been designed to operate with the antennas listed below which have a
maximum gain of 2 dBi. Antennas not included in this list or having a gain greater than 2 dBi are
strictly prohibited for use with this device. The required antenna impedance is 50 ohms.
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 permitted
for successful communication.
