Four-Way Coupler:
SRD-CPL-4
Introduction
The SRD-CPL-4 is a four-way passive coupler optimized for use in
configuring a multi-port splitter using up to four SRD-SPL-4 Four-Way
Amplified Splitters (sold separately) as part of a Crestron®XM or
SIRIUS®satellite radio distribution network. Four F-to-F cables, 1 foot in
length, are included for connection between the SRD-CPL-4 and each
SRD-SPL-4, enabling connection to up to 16 satellite radios.
NOTE: The SRD-CPL-4 is designed for indoor or outdoor mounting.
Block Diagram
The diagram on the following page illustrates a typical application using
the SRD-CPL-4 to connect to four amplified splitters feeding sixteen
radios.
NOTE: In this typical layout example, the sum total of all the cable
segments between the line amplifier output and the most distant radio
should not exceed 275 ft.
