Limitations in Japan
Note
Limitation of the radiated power (ARIB)
RF600 systems that are put into operation in Japan must not exceed the following radiated
power with an RF650A antenna:
•
500 mW EIRP (or 27 dBm EIRP) for operation with RF650R (ARIB STD-T107)
•
4000 mW EIRP (or 36 dBm EIRP) for operation with RF680R/RF685R (ARIB STD-T106)

Antenna patterns
Transponder alignment
The RF650A antenna has a circular antenna. With a circular antenna the alignment of the
antenna axis of symmetry changes between horizontal and vertical each time it transmits.
For this reason the alignment of the transponder polarization axis (horizontal/vertical) is
unimportant. Make sure, however, that the transponder is aligned with the antenna.
