I designed my station controller over 20 years ago. Since I'm a
hardware designer, it's all hardware. I suppose, however, something like
your Arduino could be programmed to read the antenna switch and send a
serial command to the amplifier, though that seems a lot of trouble.

My switch uses an Arduino to read the band lines from the K3 and
select the last antenna(s) used on that band. It the code could easily
be modified to tell an antenna tuner -- in the K3, an amp, or separate
-- which antenna system is in use. Manual switching is with a button
for each antenna.

Another advantage of doing all the antenna switching external to the
amplifier is it allows using a single coax, which can easily be
disconnected when there's lightning about.
In my case, it minimizes the number of coax runs, which keeps my wife
happy.
My system, for example, has a toggle switch to select one of my two
tribanders. I can switch back and forth several times in a second
when trying to determine which direction the signal is coming from.
I can't possibly manipulate more than one switch that fast, nor to I
want to have to reach over to wherever the amplifier happens to be,
and I certainly don't want to be messing around with a mouse. (While
all this antenna switching is going on, the other hand is running the
radio.)
