6.5.5.1 Alignment of transponders to the antenna
Polarization axis
Since the RF642A antenna has linear polarization, it is necessary to consider the alignment
of the transponders with regard to the polarization axis of the antenna.
The polarization axes of antenna and transponder must always be parallel. The symbol on
the antenna indicates the polarization axis.
