Here's my tuner setup.
Starting from the radio, the signal goes to a 4 to 1 coax switch (this
allows me to select among different radios).

tuner, I have an oil filled dummy load for amp tuning.
Finally it goes out to the antenna (actually it goes to a remote antenna
relay at the base of the tower).
When running with the amp off, I put the Palstar in the untuned settings
(bypassing it), I use the LDG tuner if the selected radio doesn't have a
built in tuner (such as my Pegasus and Orion). I have found that the
internal tuner in my Icom 746 Pro can handle any SWR that my antennas have,
so I don't use the LDG with it.
With the amp on, I use the Palstar to tune the antenna. On some
frequencies, the amp input SWR seems a little high, so I sometimes use the
LDG to tame it, but usually I only use one tuner at at time.
