APPENDIX – RECOMMENDATIONS FOR WORKING WITH GATEWAY
ANTENNA MOUNTING RECOMMENDATIONS
The Antenna included in the scope of supply has fasteners for installation on a mast
support. To ensure maximum communication range, follow the installation guidelines for the
antenna:
1. Install the antenna outside, preferably on the roof of the building (the higher - the
better, depending on the surrounding buildings). Installing the antenna in the room significantly
weakens the sensitivity of the antenna.
2. The installation site shall be as far as possible from the cellular antennas. Antenna
tuning requires the maximum distance from other antennas. After tuning and testing, antenna
can be brought back closer to the cellular antennas, if the quality of the communication is
satisfactory.
3. The antenna shall not stand in the proximity to obstacles (about 2 meters from railing,
walls, etc.). The sensitivity towards the obstacle weakens.
4. The gateway shall be installed in the proximity to the antenna – at the length of the
antenna coaxial conductor. Increase of the cable length between the antenna and the gateway
will result in a loss of antenna sensitivity.
For example, 25 meters of RG-58 cable attenuate the signal by 14 dBm, i.e. if
transmission power is 14 dBm (25mW), the power on the antenna will be 1mW
5. The antenna directional pattern shall be considered. In the horizontal plane, the
antenna has a circular direction, but no vertical direction. Therefore, the quality of
communication directly under the antenna will be worse than at some distance from the
antenna.
