This device has been designed to operate with the antennas listed below, and having a
maximum gain of 12 dBi. Antennas not included in this list or having a gain greater than
12 dBi are strictly prohibited for use with this device. The required antenna impedance is
50 ohms.
Approved Antenna List:
1. Cushcraft S2401240P12NF
2. Nearson S151AM-2450S
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.
