I'm not familiar with the TS-830 so I assumed he had a real problem.
It's a sub-set of the same problem I solved with my 20m rotatable
dipole. I provided the same solution I presently use and with it he
gets the added bonus of 20m-10m operation. BTW, 13 cent/ft 450 ohm
ladder-line with a 9:1 SWR is a lot less lossy than 13 cent/ft coax
with an SWR of 1:1. He gets all band operation above 14 MHz and greater
efficiency for half the price. Why is that over the top? :-)

Hi again, Cecil...
I think the "problem" here is that you tend to superimpose your
priorities over those of the original questioner:
"I know that I can only use it close to the cut frequency, but want
to build a small tuner to allow me to go off the cut slightly.
I only want the tuner to be used on 20m..."
Multiband operation, while desirable in my book, was not
something Kevin asked for. He also did not say he wanted
the cheapest possible feedline.
As to loss, if Kevin needs as much as 100 feet of feedline, and
wants to use a conveniently small cable like RG-8X, he can
expect to lose 1.5 dB or so. That might be a dB or so worse
than window line--if the latter is in a favorable environment.
Kevin would need mighty sharp ears to tell the difference.
73, Ed
