4.1 Standard Installation
The recommended installation for the L-SA4 SHD Antenna is the desktop configuration. Its thin
shape is ergonomically designed for discreet use at the circulation desk for multiple check-in/out
operations.
The L-SA4 SHD Antenna is designed for indoor use.
4.2 Desktop Configuration
The antenna is specially designed to operate:
• On wooden, synthetic or metallic desks (or those including metallic parts),
• In close proximity to other antennas.
Place the antenna on the desk and connect the BNC connector to the RF output of the L-P101,
Medio P200L or L-L100 readers.

4.3 Active Area in Desktop Configuration
Due to the magnetic field radiated by the antenna, a restricted area must be preserved around the
antenna to prevent unwanted reading or programming tags during check in and check out
operations.
Items must be kept out from the limited active area as shown in Figure 3.
CAUTION: Always ensure that the reader unit is switched off before connecting or
disconnecting the antenna. Also, the antennas MUST be connected to the reader unit
before it is switched on.
For optimum performance, always ensure that all metallic or conductive parts are
located under the antenna.
Do not shorten or extend the supplied cable as this may affect performance.
Do not place the antenna cable close to other cables, especially power cables.
