example, when mounting antennas on the outside surfaces of a building to provide coverage to outdoor spaces in front of
the building, a directional antenna can be used to direct the coverage away from the building.
High Mounting Omni-Directional Antenna Scenario (AP-ANT-80 vs. AP-ANT-90)
The AP-ANT-80 shows greater horizontal range due to its higher gain (8 dBi vs. 3 dBi) antenna, but in this very high mounting
situation, the AP-ANT-90 may be a better choice for ground level coverage because the direction of maximum gain is
directed downward toward the ground. This situation could potentially be improved if a lower mounting elevation was
available for the AP-ANT-80, ideally about
5 m above Ground.
