Description The GS18 GPS Splitter is a one‐input, eight‐output GPS device. This product typically finds application where an input from an active GPS roof antenna is split evenly between four receiving GPS units. In this scenario, the GS18 can be configured to pass DC from an RF output (J1) to the antenna input port in order to power an active GPS antenna on that port. The others outputs would feature a 200 Ohm DC load to simulate an antenna DC current draw for any receiver connected to those ports.
