Is the impedance of of your antenna flat from 160-10M or does it
vary from below 50 Ohms to the hundreds or perhaps 1,000's of
Ohms?
The Tuner will handle that but will your plate tuning circuit?

Rather than put an antenna tuner in series with my amp, why not add a
wide band RF impedance transformer to the output of the amp and go
directly to the feedline? Seems that adding the plate tuner in series
with the antenna tuner is just compounding losses. For example, I run
450 ohm ladder line to my (non-resonant) antenna. It is now fed by a
balanced-balanced tuner (2 26uH motorized rollers and 2 500pF variables
that can be moved from input to output as Z determines) that is fed by
my solid state 50 ohm out rig. It seems to me that I could just design
the plate tuning circuit to match 4k to 450 and add a 1:1 current mode
BALUN to the output of that and be done rather than going from 4k to 50
to BALUN to 450 as would be the case with the current 50 ohm output
designs.
Am I missing something here?
