Rear Panel Connectors
The rear panel features the following connectors (PPS IN only available on PolaRx4TR_PRO).
1.1.1
MAIN (TNC)
Connect an active GNSS antenna to this connector. The gain at the connector (antenna gain minus cable
losses) must be in the range 15 to 50dB.
By default, the receiver provides a 5V DC supply on the MAIN connector to feed the antenna. Other
voltages can be imposed through pin ANT_EXT of the IN connector on the front panel (see section
1.2.6). The maximum supported current is 200mA.
