Placing the Antenna
Pay attention to below conditions when mounting antenna.
Keep the distance from the objects that may cause the multipath effects (such as
buildings, trees, reflective surface) for at least 200 m.
Clear sky above 10 degrees elevation.
Away from electromagnetism interference region at least 200 m.
Mounted 2m over any nearby signal reflectors.
Mount stability that is not influenced by thermal expansion, wind loading, or soil
expansion/contraction.
