Figure 29 Installation points for the Bar Antenna

•

 

Orient the Bar Antenna so that the radiation field provides
maximum coverage of the access or monitoring area (door), etc.
Keep in mind what will be tracked with the antenna – personnel
would carry Tags in their shirt or pants pocket, Tags on laptops
would be carried closer to the floor. The read-range for the Bar
Antenna is about 8 to 12 feet.

IMPORTANT!

 Test each position shown in Figure 29. Tilting the

Bar Antenna may also improve performance.

If mounting the Bar Antenna on the ceiling, mount it flat with the
front of the case pointing at the floor.

•

 

If applicable, follow the guidelines in the manufacturer’s
documentation for placement and wiring of any controller or
peripheral device.
