Usually, when the impedance/VSWR changes a large
amount, or the axe shorts the center to the outer
conductors, the transmitter will fault and shut down.
It may try to recycle a couple of times, but that's
about it. They usually do a good job protecting
themselves.

I was working on some station wiring and plugged in a
control box that had (unknown to me) latching relays.
As soon as 120VAC was available, they dutifully
activated the coaxial switches, putting the antenna on
the other transmitter. There was a very loud crack
from the transmitter as it arced and shut down; scared
more than the s**t out of me, since that put the
station off the air. The other transmitter was all
apart and being cleaned. All I had to do was command
the coax switch from the remote control to put it on
the backup transmitter, then hit the Plate On, and
things got running again. Taught me a lesson though.
