  • 【Description】

    The GS14 GPS Splitter is a one‐input, four‐output GNSS splitter device. This product typically finds application where an input from an active GPS roof antenna is split、 evenly between four receiving GPS receivers.

    The GS14 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 second, third and fourth RF outputs (J2,J3, & J4) would feature a 200 Ohm DC load to simulate an antenna DC current draw for any receiver connected to those ports.

    The most common application is the input from an active GPS/GNSS roof antenna or GPS simulator is equally split to four receivingg GPS units. The GS14 will support long-lasting, trouble free deployment in a small cell wireless and/or CORS center stations. The device makes it possible to use a single GPS/GNSS referencing antenna for synchronization systems, increasing capacity without increasing GPS/GNSS antennas or cabling requirements.

    GS14-S utilizes an aviation power plug for power supply, both internally and to the GPS antenna. In the standard configuration, the output ports do not have a 200Ω DC load.

    The wiring method for the aviation plug interface is as follows:  Connect the A-end to the positive pole of the power supply, connect the B-end to the negative pole of the power supply, and the C port is a reserved wiring port with no function. The power supply voltage range is 12V~28V. Power consumption is <0.5W.
