Alignment of transponders to the antenna

Polarization axis

Since the RF615A 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.
