Four-Way Amplified Splitter:
SRD-SPL-4
Introduction
The SRD-SPL-4 is a high quality amplified splitter optimized to split a
single antenna signal to feed up to four satellite radio tuners as part of a
Crestron
line amplifier is rated to provide 8 dB (minimum) of gain in the satellite
radio band (2320-2345 MHz), and is powered from the DC bias voltage
(4.5 VDC to 6.5 VDC nominal) provided by the antenna connections on
any of the satellite radio tuners downstream. It is also designed to pass
DC voltage to provide power to the antenna and other line amplifiers
installed upstream.
Accessories furnished with the SRD-SPL-4 include four 3-foot F
(female)-to-SMB (male) adapter cables, four F (male)-to-F (male)
couplers, and one SMB (female)-to-F (male) adapter. Standard RG-6
cable with male F connectors (not supplied) may be used to extend the
output cable length up to 70 feet from each individual output to each
satellite radio tuner. Adding an SRD-AMP-1 line amplifier (sold
separately) at the input of the splitter will enable longer output cable
lengths of up to 200 feet each.
®
XM or SIRIUS® satellite radio distribution network. Its built-in
NOTE: Unused outputs do not have to be terminated for proper operation.
A 20 dB power passing attenuator is also included for use in preventing
overload of the splitter input in any installation that is located near a high
power satellite radio terrestrial repeater.
NOTE: The SRD-SPL-4 is designed for indoor or outdoor mounting.
