Rear Panel Connectors
The rear panel features five connectors.
2.1.1
MAIN and AUX (TNC)
These are the main and auxiliary antenna connectors. Connect active GNSS antennas to these
connectors. The gain at the connectors (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 and AUX connectors to feed the
antenna. Other voltages can be imposed through pin ANT_EXT of the IN connector on the front panel
(see section 2.2.6). The maximum current for each antenna is 200mA.
Never inject a DC voltage into the MAIN connector as it may damage the receiver. For instance,
when using a splitter to distribute the antenna signal to several receivers, make sure that no more than
one output of the splitter passes DC. Use DC-blocks otherwise.
