EXPANSION MULTICOUPLER WITH BNC CONNECTORS
INTRODUCTION
The Expansion Multicoupler is a wideband low loss 8 way splitter with high isolation
between outputs and is available as an optional accessory for the range of Receiver
Multicouplers to expand system channel capacity. The Expansion Multicoupler is
designed for broadband operation and is suitable for use with all models in the RFI
Receiver Multicoupler range.
INSTALLATION
Mounting
The Expansion Multicoupler is to be mounted indoors only. It is designed to fit in a
1RU rack space and should be mounted clear of any equipment that generates
excess heat.
Earthing
Compliance with international electrical safety standards requires that the external
Protective Earthing point on the Expansion Multicoupler, as indicated by this
symbol, be permanently hardwired to the premises protective earth system using
1.5 mm2(14 AWG) minimum cross-sectional area conductor. This connections
provide protection from hazardous and transient voltages.
RF Input
The specified maximum signal level into this input should be observed to avoid
damaging the input circuitry.
RF Outputs 1 to 8
Eight equal level BNC connector RF outputs are available. Best performance will be
achieved if 50 ohm terminations are fitted to any unused RF outputs however, as the
outputs are well isolated from each other, the performance degradation is minimal if
the unused RF outputs are left unterminated.
Cabling
Please ensure that all cables to the Expansion Multicoupler are properly grounded to
avoid lightning transients travelling to the unit. If the Expansion Multicoupler is located
some distance from the Receiver Multicoupler longer cables will be required. Only use
high quality, well screened coaxial cables between units.
Connecting to the Receiver Multicoupler
Connect the supplied BNC(m) to BNC(m) cable from the Receiver Multicoupler
Expansion Port or RF Output (as determined by configuration) to the RF Input on the
Expansion Multicoupler.

Using Multiple Expansion Multicouplers
In systems where more than 16 outputs are required up to 17 Expansion
Multicouplers can be used with one Receiver Multicoupler. Using multiple units, up
to 128 equal level outputs can be provided.
