4.3 Antenna Installation
General recommendations for antenna installation:
Try to keep the LOS clear of obstructions. In case of installations over vegetation and forest, make sure the
direct LOS stays above the trees; in urban environments - above the tallest buildings along the radio path.
The influence of trees can be variable, depending on the season (ice, dew, leaves). Keep in mind that, during
spring and summer, leaves can absorb high levels of radio energy. Therefore, when installing during the cold
season, over forests and trees without leaves, try to achieve a higher fade margin.
Before installation, make sure the devices are located outside the area of water streams and splashes
formation, which can affect the enclosure for a long time.
Install antennas as far as possible from other antennas (the recommended distance is at least 2 meters
between edges of the antennas).
Reflecting surfaces should be considered (buildings with reflective windows, water surfaces or wet grounds).
These can be useful in NLOS situations, if there is no direct clear path between the 2 antennas, so the radio
signal needs to be reflectedby a surface. However,reflections can also decrease the signal quality when
encountered along a clear LOS link, because of fading caused by multipath propagation.
When installing antennas over the water, tune the height bracket within a1-3 meters range variation,
because it can yield significant signal level variations due to multipath fading.
