Connect a splitter, input to the RX Ant Out jack, one output to the
RX ANT IN jack and the other output to the Antenna input of your SDR.

Press the RX ANT button to activate the RX ANTENNA Out/RX ANT IN path.

Yes, the RX ANT Out/IN path is on the receive side of the T/R switch.
There is no RF (or only leakage) present in transmit.
