- 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.
- Install antennas as far as possible from other antennas (the recommended distance is at least 2 meters).
- 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 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.
- Weather factors such as rain or snow do not usually affect system performance. If seasonal changes influence the signal quality, then the connectors probably are not protected well enough from humidity, or the cables, connectors or antennas are covered by vegetation during summer or ice during winter.
