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.)
