At the very end of your plot, you might squeeze in 50 MHz, 6-meters, as
well where you should not need a tuner.

You're certainly looking good at 40 and 15 meters. Also at 36 MHz where
we don't have an allocation. Looks very good!
Now, you might zero in on both 40 and 15 meters and do a measurement of
those bands to assure you are less than 3:1 over the whole band. Set up to
scan 7.000 to 7.300 MHz (40-meters) and 21.000 to 21.350 MHz (15-metes).
That will tell you whether the internal tuner in the Kenwood will correct
for SWR. I have the TS-2000X and its internal tuner will properly match up
to and including 3"1 SWR, but not much more. Most of the internal tuners
stop at 3:1.
On your return loss plot, only these two amateur bands show less than 6 dB
which is an SWR of 3:1. So, you are limited to those bands.

I have the antenna spooled out to exactly the 7Mhz silver markers on the
wire here is the readings on the antenna with my homemade choke on it. Not
sure what other improvements i can make yet. Based on the readings are
there frequencies i should not transmit on I really don't know how the AT
unit works in the kenwood and how much range it has to correct SWR.
