CPDC4X1 GPS Combiner

GPS Networking – CPDC4X1 GPS Combiner 4X1 – 4 Inputs – 1 Output

Manufacturer: | Categories: ,

The CPDC4X1 GPS antenna combiner from GPS Networking is a four input one output power divider designed specifically for the GPS L1, L2 and GLONASS carrier frequencies. The CPDC2X1 allows you to put four antennas on one GPS receiver.



The CPDC4X1 GPS Combiner (GNSS Combiner) is a four input, one output device. The frequency response covers the entire L-band (all GNSS Frequencies) with excellent flatness. In the standard configuration, DC is passed from a connected GPS device through the combiner to both inputs (antenna ports). The connected GPS device or receiver will continue to maintain a GPS lock in the event of an antenna failure.
