If no transponder is
identified, first increase the radiated power as described in the
following section. Then repeat the antenna adjustment.
Also check the polarization of your antenna. If the transponder always has the same
alignment, the antenna polarization should be adap
ted accordingly. If the transponder
moves or the alignment of the transponder varies, it is advisable to combine several
antenna polarization types or to select a circular polarization.
5. Optimize the antenna adjustment until the maximum possible RSSI value is reached.
6. Secure the antenna.
