Antenna Location
Proper antenna location is essential for the best system performance and maximum
range. Antenna positioning is important with all RF systems and in all applications.
Locate the Tempest BaseStation antenna as high as possible for your application
to maximize line-of-sight RF operation. Positioning the antenna higher than head
level is the minimum acceptable height for most applications. Maintaining line of
sight between the BaseStation antenna and the BeltStation(s) is ideal.
When using multiple BaseStations, keep as much space between the antennas as
possible, but at least twenty-four inches is recommended. Increase the distance
between antennas to improve performance.
If possible, locate the antenna(s) away from any metal obstructions and away from walls or other significant structures, by
at least 24 inches.
When using omni-directional (Whip) antennas always locate the antennas as close to the center of the coverage area as
possible. Omni-directional antennas have a circular pattern and radiate RF energy equally in all directions at approximately
a 90° angle to the element of the antenna.
Other antenna options are available including directional and higher gain antennas. Please contact your dealer or distributor
for more information on optional antennas. Only use approved antennas. Unauthorized antennas may be illegal.
Using more than one BaseStation permits an increase in the number of wireless BeltStations within an area, or by utilizing
the iSelect roaming feature, allows increasing the area covered and even allows for the creation of separate but adjacent
or overlapping coverage areas. The number of BaseStations that can be utilized in a system is limited by RF competition
between systems and several other RF conditions. Judicious placement of antennas can help facilitate a large number of
wireless BeltStation users on a single system.

When rack mounting the Tempest BaseStation or when it is stacked with other equipment
always remote mount antennas or use the Tempest Remote Transceiver to assure
maximum operational range.
