4.2 Direct Mount Antenna
m WARNING
POTENTIAL ELECTROSTATIC CHARGING HAZARD
The direct mount antenna radome is made of plastic and has a surface resistance greater than 1Gohm per square. When the
Series transmitter is installed in potentially hazardous locations care should be taken not to electrostatically charge the surface
of the antenna shroud by rubbing the surface with a cloth, or cleaning the surface with a solvent. If electrostatically charged,
discharge of the antenna shroud to a person or a tool could possibly ignite a surrounding hazardous atmosphere.
4.2.1 Direct Mount, General Guidelines
A direct mount antenna (either straight or tilt & swivel) can be easily mounted by threading the mating RP-SMA plug of the antenna to the
RP-SMA jack on the WPS. Tighten the connection until finger tight. For straight antennas, either 0 dBi or 2.0 dBi, attach the antenna ra-
dome with the two screws provided. Insure that the "O" ring is installed in the grove in the sensor housing.
If a radome is not used, and the antenna is in an exposed location, the antenna connector barrel and exposed threads should be protected
from the elements with a weathering tape (such as COAX-SEAL #104 from LComm, or Super 88 tape from 3M).
4.2.2 Direct Mount, Straight
Figure 4. Direct Mount Antenna
Option 01
Straight antenna available in 0 dBi or 2 dBi configurations.
If the sensor is using the direct mount straight antenna you can adjust its position by mounting the sensor with a 45 or 90 degree elbow.
Typically, pointed straight up gives best performance but your installation may vary. Generally, the 0 dBi antenna will be less sensitive to
antenna orientation, and higher gain antennas will be more sensitive to orientation.
