Some newer rigs like the Icom !C-7410 do not have a separate RX antenna 
input.  One reason was probably  that the close proximity of a TX 
antenna would often take out front ends.  I currently use the DXE RTR-1 
to do the switching for me.  There are other units on the markets but 
the DXE has been well engineered to protect front ends even with cockpit 
errors.  I have also used the MFJ-1026 noise cancelling box which has RF 
sensing and hard drive TX/RX capabilities.  The RX antenna bank just 
hooks up to the noise antenna port and with front panel controls you can 
have either antenna, or have both, and even phase them for noise 
cancellation as you may require.
