Alignment of transponders to the antenna

Polarization axis

Since the RF622A antenna has linear polarization, it is necessary to consider the alignment of

the transponders used in relation to the antenna.
The polarization axes of antenna and transponder must always be parallel. The symbol on the

antenna indicates the polarization axis.
