If tuning for 160 meters is different than for the HF bands, then I'll
wait until I actually have my General class license before I start
thinking about that.

Tuning is no different on 160 compared to anywhere else. It is just that the
very long wavelength makes short antennas difficult to match, and be outside
of the range of that particular tuner.

I have about 45' of end-fed wire that I can match on 160m to a low swr with
the auto atu that I have. Of course that does not mean that it makes an
effective antenna, but I can work people on at a push.
