Safety
The antenna and all associated equipment should be installed with all
applicable local and national electrical code guidelines to ensure safe
operation.
Location
For best results, mount the antenna above exterior obstructions in a
location near the center of the coverage area. A line-of-sight path
between the antenna and active locations generally works best.
Although frequency signals penetrate cubical dividers, partitions, and
interior walls with little attenuation, reinforced block walls, metal
surfaces, and steel shelving may attenuate signals or cause multipath, a
condition where reflected signals interfere with the primary signal path.
Avoid mounting the antenna next to a column or vertical support that
could create a “shadow zone” of reduced coverage to one portion of the
room.
Avoid installing antenna on a metal-backed ceiling or metal structure for
best performance. Any metal structure may detune the antenna. If
installation below metal structure is unavoidable, a minimum distance of
75 mm from the metal surface is recommended.
Precaution
To avoid damage of the connector joint, use the correct size of wrench
to hold the connector body shell properly during tightening. Use an
18mm wrench for the 4.3-10 connector, torqued to 44.3 lbf∙in (5 Nm).
For best PIM results:
•Make sure the connectors are clean and free from any metal
flakes/dirt, and tighten the connectors using torque wrench.
•Avoid extreme bending to the cable.
•During installation of the antenna, both cables should not be crossing
one another.
•Do not remove the dust cap from connectors when not in use.
