Mounting the transponder on or in metal is only possible with the appropriate spacer or if there is
adequate clearance to the metal.
4.3.5 Installation and connection of 2 to 6 antennas with one reader
If several antennas need to be operated on one reader, this can be achieved by using the
antenna splitter. Up to two antennas can be operated on the RF285R readers by using an
antenna splitter, and up to four antennas can be operated on the RF290R readers.
Note that the antenna splitter is a purely passive device that splits the power at the input to
two outputs and therefore halves it. This is possible both in PC mode (RS-232) and CM
mode (RS-422). You can cascade the antenna splitters in such a way that up to 4 antennas
can be connected at the same time.
