Back to TX distance - you really need to get a good book on propagation and
understand the solar cycle and the characteristics of each band.

For example -- on 10M with the right time in the 11 year solar cycle -- a
minimum antenna and a few watts will work the world (at the right time of
day)

On 160M in the day time in the summer with low power -- you ain't going
anywhere

And single-banded, one thing a tuner is not. :-)

The antenna need not be resonant. Under certain easily obtainable
conditions, the length of the open-wire transmission line can tune
a non-resonant antenna to system resonance and better the losses in
the coax feeding a resonant antenna. How to do that is described
on my web page.
