This device has been designed to operate with the antennas listed below, and having a
maximum gain of 2 dB. Antennas not included in this list or having a gain greater than
2 dB are strictly prohibited for use with this device. The required antenna impedance is
50 ohms.
Proper antennas are:
Pulse/Larson Dipole Antenna
Part Number: SPDA24850/1900

Antenna Extensions

Coaxial cable can be connected to the standard SMA antenna connectors to extend the placement distance
of the antennas from the 3G NIM base unit. Using cables introduces signal loss in the antenna system, but
can be minimized by minimizing the length of cable used and using low-loss or ultralow-loss antenna
cables. Cables that do not match the antenna specifications are strictly prohibited for use with this device.
Using improper cables may hinder the ability of the 3G NIM to communicate with a
cellular network. Refer to the documentation accompanying your cables to ensure you
have the right cables for this usage and that the cables meet the requirements specified
above.
