has a gain greater than 5dBi, are strictly prohibited for use
with this device. The required antenna impedance is 50 ohms.
The antennas that can be used (country dependent) with the
460 MHz radio are 0dBi and 5dBi whip antennas. The antenna
that can be used with the GSM radio is the 0dBi whip antenna.
To reduce potential radio interference to other users, the
antenna type and its gain should be so chosen that the
equivalent isotropic ally radiated power is not more than that
permitted for successful communication.
