[Elecraft] K3 RX IN/OUT and Splitters

I am want to split my BOG RX antenna between my K3 RX IN jack and the ANT
port on my AFEDRI-LAN SDR at my remote site.  I am going to access the SDR
remotely using SDR Console and run CW SKIMMER on the ARRL DX Contest PC in
the home shack.  My K3 has no built in Tuner and no 2nd RX.

I have been  looking at various schemes people are using to split antenna
feeds.  Some are using a splitter between the RX IN/OUT jacks on the K3.
 What is the point of doing that?  The MAIN Ant port is always used as TX
antenna.  When  RX  ANT (Tap) is activated the RX IN Port is connected to
the RX/TX and the MAIN ANT Port is connected to the RX OUT port.   I see
people talking about the RX ANT "LOOP" .  As far as I can see there is no
RX ANT "LOOP".  What is the point of the splitter between those those two
jacks.?  The jacks are labelled RX IN and RX OUT.  The labels imply that
the RX antenna also appears at the RX OUT jack but that is not the case.

I am just going to connect a BNC "T" in the BOG RG6 line at the radio  and
feed the K3 RX IN port and the AFEDRI-LAN ANT port.  If that doesn't work
satisfactorily ...I'll use a passive splitter in the RG6.

Am I on the right track?
