[Elecraft] Thanks! OT: Vertical doublets / baluns / tuners

[Joe - aa4nn]

Hi 'Crafters, I  have an experiment here with a doublet.

Take 50ft of zip cord.  Split apart 22 ft to make the overall horizontal
length be 44 ft.  The remaining unsplit 28 feet is the vertical parallel
feedline to the shack.  Center height is 17 feet, two ends are at 10 feet,
inverted "V".  I have a 12 inch stub of RG8X with 5 ferrite beads on it.
PL259 on one end of the stub and alligator clips on the other end.  I use
the alligator clips to connect to the zip cord feedline and I attach the
PL259 to the KAT100 tuner.

Now this KAT100 tries its best to tune, and on 10m through 40m it is not
bad.  But am I not missing something.  Wouldn't some kind of maybe a 4:1
balun be needed to go between the balanced parallel feedline and the
unbalanced tuner output.  ??

I'm looking for a simple K2 Field Day setup.  Thanks.
