adequate clearance to the metal.

Installation and connection of 2 to 6 antennas with one RF290R reader
If several antennas need to be operated on one reader, this can be achieved by using the
antenna splitter or the antenna multiplexer RF260X.
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.
The antenna multiplexer RF260X works only in PC mode (RS-232) in time division multiplex
mode. This means that each antenna operates with full power for a certain time before the
device moves on automatically to the next antenna. The antenna multiplexer normally
operates in scan mode or buffered read mode which with suitable parameter assignment add
the information about the antenna number to the reply of the transponder. You can operate
up to six antennas on one reader via the multiplexer.
