Pass the DC to the input port from J1 only
The MGS12 GPS Splitter is a one‐input, two‐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 MGS12 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 output (J2) 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 two receivingg GPS units.
The GS12 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.
