Hajo,
The T1 tuner has a wide range. The total matching range will be greater
on high bands and less on lower bands.
Both the T1 and the KXAT1 (and other tuners) specify the matching range
in terms of the maximum L and C available. That is a more exact way of
stating the range than stating SWR capability.
The KXAT1 is the most limited because it has only 3 inductors and 3
capacitors to choose from. It is optimized for the antenna shown in the
KXAT1 manual. On 80 meters it may need some extra help with a series or
parallel inductor or capacitor external to the tuner.
If you are really ambitious, you could take the maximum inductance and
capacity and run it through the formulas for an L network and obtain the
matching capability for any frequency. The inductors are series
elements and the capacitors are shunt elements which can be switched
from either the input side or the output side.

Hello,
in another thread was said, that the auto-tuner of the new Icom had a 3:1
VSWR. I was looking up and down the net and didn't find any comparable
figures for the KxATu and the T1.
I know that I can match a wet towel, so could someone enlighten me and give
some numbers?
