4. Antenna Precautions
If the antenna is to be mounted outside, consider the risk of lightning. Follow the instructions provided
by the antenna manufacturer.
• Never connect more than one modem to a single antenna. The modem can be damaged by
radio frequency energy from the transmitter of another modem.
• Like any mobile station, the antenna of the modem emits radio frequency energy. To avoid
EMI (electromagnetic interference), you must determine whether the application itself, or
equipment in the application’s proximity, needs further protection against radio emission and
the disturbances it might cause. Protection is secured either by shielding the surrounding
electronics or by moving the antenna away from the electronics and the external signal cable.
• The modem and antenna may be damaged if either come into contact with ground potentials
other than the one in your application. Beware: ground potentials are not always what they
appear to be.
