User Guide, WherePort IV D1300 REV A

Figure 137 and Figure 148 show two ways of solving the problem. The example in Figure 137 uses a
WherePort IV to cover two doors. Since these WherePort IVs are mounted in different orientation on the
walls, their phases must be set as well. Figure 148 shows a WherePort IV mounted above each door. The
phases for these ports can all be set to 0 but they must still be phased together with one of the ports
identified as the master.
The orientation of the tags will also affect the location of the WherePort IVs. If the tag orientation is
horizontal, then the top solution is best so that the WherePort IV field will be maximized. If the tags are
oriented vertically, then the lower solution, with the WherePort IVs mounted over the doors, will be best.

The dotted line ellipse shows the approximate shape of the coverage area if the tag is oriented
horizontally rather than vertically.
