• Avoid installing the antenna in a place where it can be shielded, covered or mounted in a closed
metal cabinet since it might weaken the performance.
• Use only dual-band (900 MHz and 1800 MHz) GSM antennas.
• Avoid placing the antenna right next to power cables, since it might disturb the signal.
• If a long antenna cable is required, please contact Kamstrup A/S to obtain a “super low loss”
antenna cable (order No. 6699460).
