I am sorry for any confusion. But I used that antenna on the Maldives Isl.
and from D4 (Cape Verde) with great success.
3200 + QSOs as D44TUK on CW and 1400 as D44TUQ (my YL) on RTTY was
verifying that.
To answer your question now, I have seen that combination with the 4:1
balun at one of our
competitors in the IARU Fieldday Contest. That was before K3 when the
Kenwood TS 850S was the
first choice of serious contester.
I love that marvelously performing ANTENNA TUNER in my K3

Out of curiosity, why did you choose to use a 4:1 balun with that
antenna/feed line configuration and not a 1:1 balun?
I have a center fed wire fed with 450 ohm twin lead window line and I
use a 1:1 balun which I'm told is correct.

On my holiday style operations I use a doublet with 300 Ohm twin lead
cable.
The end of that 300 Ohm feeder is connected to a 4:1 BALUN
The BALUN is hooked direct to the K3S / K3
With the internal ATU I can use that antenna from 10 to 80 with 100
Watts
For details have a look to http://www.dl2mdu.de/antenna/

I would disagree. Most high power commercial operations use
non-resonant mismatched antennas. Typically there is either a tuner
at the antenna or open wire is used.

If an antenna is showing a VSVR of 3:1, something about the situation
is wrong, and most likely it's -not- the antenna. Fix the problem

the antenna power where it's resonant, assuming the antenna is
actually
resonant on the amateur band of interest. Expecting a tuner to
compensate
for a problem external to an antenna is unreasonable, IMO
