I believe he is actually operating into an antenna on Ant1 port. He
switched to Ant2 to check the port isolation and would obviously switch
back to Ant1 to operate. I doubt grounding the non-selected antenna
port would make any difference on TX and some use both ports for
diversity RX. If protecting the radio is the concern then I believe as
Kent stated, the dummy load would be the best option.

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?
