I am going to put up a 40 meter dipole soon. I will work 40-10 meters with this antenna.
As the location is good distance from the shack I thought I had better us 450 ohm ladder line to avoid loss.
I thought I would use a Kenwood AT-230 tuner but I am not sure it's set up to use the ladder line directly on the ANT-3 input and the ground terminal.
Is this install going to be OK or should I use a short coax run with a balun from the end of the ladder line and use the coax inputs on the tuner?

You need an external balun, for certain.  The AT-230 (I have one) is for unbalanced antennas only.

If you try to use it with ladder line, you're in for bad surprises.

That's what I thought looking at the circuit.
So balun it is.
Thanks.
