Overview
GPS Source’s C21 Galileo/GLONASS/GPS combiner is an RF device with two inputs and one output. Primarily, it is used for receiving input from two different GPS antennas, merging the data into one signal, and sending it to a GPS receiver.
This means the C21 can relay direct current from a radio frequency output to its two (J1 and J2) antenna input ports so that the GPS antennas active on its ports have a power supply.
The unit comes with many options for configuring according to user needs. When the powered option 1275B is purchased, the maximum direct current in is 35 Volts. When the powered option is delivered with a wall mount transformer, voltage input is 9 Volts.
Features
