[Elecraft] KRX3 antenna input

[jeff kb2m]

 I spent the morning installing a sub rx in my K3 #1516. All is working 
well. I set it up using the KAT3 ant2  as input the the sub rx. Now I'm 
thinking that there is no advantage to doing it this way(other then me being 
too lazy to install the aux bnc connector). Does it really matter, is there 
any advantage to using the bnc as an rx only input?  I have a four way 
antenna switch downstream from the K3 so there is no advantage to the ant2 
not being used by the main receiver as all antennas come in through ant1. 
The ant2 input would go unused otherwise. Is the bnc rx input better, is it 
worth taking my K3 apart to install the BNC rx connector ? All 150 to 400 
answers  welcome...
