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 seasons (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;
Proximity to other antennas should be avoided;
Reflecting surfaces should be considered (buildings with reflective windows,
water surfaces or wet grounds). These can be useful in NLOS situations,
where there is no direct clear path between the 2 antennas, so the radio signal
needs to be reflected off a surface. However, these can also decrease the
signal quality when encountered along a clear LOS link, because of fading
caused by multipath;
When installing antennas over water, tune the height bracket within 1-3 meters
range variation, because it can yield significant signal level variations due to
multipath fading;
If seasonal changes influence the signal quality, then the most probable
reasons would be either that the connectors are not protected well enough
from humidity, or that the cables, connectors or antennas are covered by
vegetation during summer or ice during winter.
3.2.2. Mounting Types
3.2.2.1. Pole Mounting
Antenna installation is performed on a special facility called antenna pole. The pole
is used for strong antenna tightening at the installation site. Poles might have
different modifications depending on the installation requirements.
