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.
