S18-A STANDARD HOUSING
1x8 GPS Splitter

DESCRIPTIONThe S18-A GPS splitter is a one-input, eight-output
GPS splitter device. The typical application allows theGPS signal from an active GPS roof antenna to be split
evenly between eight GPS receivers. The S18-A canbe configured to pass the DC from an RF output(OUT1) to the antenna input port in order to power anactive GPS antenna. The DC blocked ports (OUT2through OUT8) would feature a 200  DC load tosimulate an antenna DC current draw for any receiverconnected to those ports.

FEATURES

Passes GPS, Galileo, and GLONASS L1/L2
Excellent Gain Flatness
RoHS/WEEE Compliant
Designed to MIL-STD-810
Amplified to Preserve Link Margins
Available Options:– L1/L2– Beacon– Waterproof– EMI Shielding– Hermetically Sealed

OPTIONSThe S18-A GPS Splitter comes with many available
options to meet specific needs. Please contact GPS
