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

Hi All,

Thanks for all the information, there was plenty to think about, and decide
to do.

Just for the record, I wanted a simple dipole, using coax, as it is easier
to work with in my home, no windows near to run ladder-line.
I do agree that ladder-line would of made it work better across other bands
with a tuner, but I just wanted something on 20m.
The rig, TS-830S, being tube finals, from the information will allow me to
tune off the cut frequency with tuning the tubes. So I will be able to move
across the band without too much problem.

I have the dipole cut and ready to go up, was going to do it today, however
the rain came down, and washed that idea away, have to wait for the weekend
now.

Again thanks to all.

Kevin, ZL1KFM.
