Actually i testing it too on down to 80m lol never got into double digit swrs.
Weird...

Cool. OK now... how.would one achieve that black line frim 10m to 160m or below and upto 6m or it impossible using an air coil and those slipon palamar beads 31mix model BA 8, and how many to achieve it and how many turns on an air coil and how wide 4.25, 7, 8, 11 inches ect...
These beads

And how far from connector and how far after they stop start the air coil?
Really SO-239 top and bottom if I am understanding this and how many inches or feet from antenna SO-239 to current balun? And any windings needed or just slap that on and x amount of coax to balun is it?
My statement implying your chokes leed looked to be to far from the feed point was based purely on my research and the replyes to my op.
The majority of those replyes suggested the leed coming off the choke should be "as close as possible to the antennas feed point". And 2' seemed far from " close as possible" than it could be.
After writing k3dave@msn.com and asking him to advise me on this particular point he promptly answered my question. And his answer was that two feet was an ideal distance from the feed point no mater what band/bands the antenna is built and used for.
I apologize for questioning you chokes install but I hope you undestsnd why I did so. I tryed to add the link to k3dav's web page which a member actually posted within the last month.
Dave hss some interesting information on subjects related to ham and non ham radio subjects. All are interesting and insightful. His adress is-

No need to apologize, I am seeking answers and trying to gain first hand knowledge.
To me any input is welcome
Their's always someone who know it or has been their done that.
What about using this and how much coax from antenna input (SO-239) to this and or can it be used just before coming into the tuner? Or can use one on each end?

The distance from the feedpoint to the choke should depend on the frequency, i.e. the fraction of a wavelength at that frequency represented by the distance. The higher you go in frequency, the shorter the wavelength becomes. While 20" is almost 5% of a wavelength on 11 meters, it's only about 0.6% at 80.
Anyone, however, can experiment and see what difference can be repeatedly made.

The closer to the feed point of the antenna is in most cases the best place to install the choke or balun.
Reason being is to ELIMINATE the shield of the coax from being part of the antenna. TVI, RFI all caused by CMC.

What about this under the antenna via double PL-259 to connect it or how far down would you go and I take it I need NO air coil?
With that you would not need any type of rf choke
install on a short jumper as near to the feed point as you can install it with good mechanical integrity.
Keep in mind that on that I2K you will not be working 160 thru 10 meters so that part is WAY over kill but it is your set up and your dime.
On the other hand you may want to use that sometime in the future on some sort of multi band antenna but coax is the wrong type of transmission line to use for all band work into a non resonant antenna.
