3 Overview
The L-SA4 SHD Antenna allows multiple books or CDs/DVDs transactions (stack of books, stack
of CDs/DVDs)
The antenna provides a large area of detection (
Figure 1
). The L-SA4 SHD Antenna is optimized
for use with the TAGSYS L-P101, Medio P200L and L-L100 (please see Caution) readers and is
recommended for check in/out operations.
Due to its specific design, the L-SA4 SHD Antenna can be safely used in proximity with other
TAGSYS RFID products. It will work also, if properly installed; in metallic-type environments (see
Section 4, "Installation"
for more details). In this case, performance may be reduced.
The antenna is provided with rubber base pads for installation in a standard desktop configuration.
Although this antenna has been specifically designed for library applications, it can also be used
for any application requiring a desktop station which has a good immunity to its environment.
The antenna has been factory calibrated to an impedance of 50
Ω
which offers optimal
performance when the antenna is installed on the surface of a desk or table.
It may be necessary to retune the antenna once installed if the environment is highly metallic or if
the antenna is installed underneath the table or desk. For more information about tuning antennas,
refer to
Section 6.2, "Antenna Tuning"
.
Optimal performance is achieved when the smart labels to be read are placed parallel to the
antenna surface and centered on the antenna surface.
