That doesn't explain how he expects the rig to short out the port for Ant 2 . .. WHEN IT HAS BEEN SELECTED ... just because there is no actual antenna connected to it.  I don't get the reasoning behind the original query.

We hook dummy loads to ANT 2 on all our K3s during FD to prevent inadvertent 
transmissions when no antenna is connected to it.  The ATU TUNE button is 
immediately above the ANT button and fat-fingered/far-sighted ops unfamiliar 
with the K3 have been known to hit the wrong one, especially on the higher 
bands where the noise floor makes it difficult to detect the absence of an 
antenna.

If you selected Ant 2 it wouldn't have been "unused".   How is the rig supposed 
to know you don't have anything physically connected to that port?
