The arrangement of the front panel connectors of the GPD2000C01 module is shown in
the following figure.

The SMA connector identified on the front of the module as ANTENNA is the GNSS signal
input and also the voltage supply output. This connector is used to connect the module
to the antenna.
The SMA connectors on the front of the module labelled RX1+DC, RX2+DC, RX3 and RX4
are the outputs of the distributed GNSS signal to be sent to the GNSS receiver modules.
Those receivers connected to outputs with DC are the ones that can be used to provide
redundancy to the antenna power supply.
Connections between the antenna and the GNSS receivers should be made using
low-loss coaxial cable with a 50Ω characteristic impedance.
The GNSS system uses a frequency range from 1.1 to 1.6GHz. Make sure to use cables
and connectors of known quality.
The front panel has not been designed to support mechanical stress. All cabling in the
rack where the mounting frame is located should be properly supported so that the front
panel does not provide mechanical support.
