The external antennas can be connected with the antenna connectors (ANT1...ANT4) with
the help of an U.FL cable.
Figure 8: Position of the antenna connectors ANT1
– ANT4
NOTE:
Only for use with 50
matched external antennas. The permanent usage of unmatched
antennas can damage the connected reader electronic.
The antenna output is neither permanent short circuit protected nor permanent no-load
protected.
The antenna cable between reader and antenna should be in total no longer than 1 m.
The use of other cable length are possible after consulting the manufacturer.
To avoid transient emissions the switching between the antenna outputs must be done
without reader RF power on. The ID CPR74 will take care about this automatically.
