Right now I have no idea what my favourite band might be. I'll try the
basic wire, I used to try that many years ago as a kid, in places where it
was easy, on private land with space for it. But that was the seventies, in
the country. Now I'm in an inner city full of mobile phones and computers,
things have changed so much that I know it won't be the same. I like that 18'
whip scheme you linked to though, I really like that one and want to try it.

Lost-

I agree that the "basic wire" antenna approach will almost certainly
work. At least you will get your feet wet. That is the kind of
external antenna most often used with that type of radio.

If you want to continue the search for input impedance, consider trying
something like an MFJ Antenna Analyzer (MFJ-259 or 269?), which uses a
sufficiently low signal level that it shouldn't hurt the radio. Instead
of analyzing the antenna, use it to analyze the input of the radio. You
can use the information to design a matching circuit, but you may find
that the improvement is disappointing for reasons already discussed.
