Receiver Multicouplers
peRFoRMance & FuncTIonaLITY
These Receiver Multicouplers provide
unparalleled performance with the
flexibility to configure and expand as
individual customer requirements
demand.
Receiver Multicouplers should always be
linked to an appropriate Receiver
Preselector that passes the desired
receive frequencies and rejects
transmitter or other out-of-band signals.
The two-way radio marketplace is a changing landscape. The introduction of
digital technologies, shared networks, and ever-increasing expectations for
reliability have raised the bar in receiver combiner requirements.
RFI is pleased to announce the introduction of a new range of high performance
Receiver Multicoupler products targeted at satisfying these emerging
requirements.
