How does one can determine the impendance of a wire to get the right balun
for it, so it can be hooked up to the coaxial cable?

Check out the following website for how to build an 'inverted-L'
shortwave antenna with a *properly* installed balun. This design can
make a big difference in reducing local (man made) noise on your
antenna, which makes it easier to hear weak stations. I used R6U coax
which is made for satellite TV systems. It's 75-ohm (not 50-ohm) but
that's close enough for shortwave receiving antennas. I made the balun
on a T-34 ferrite core. You can get these cores from 'Amidon' or one of
their dealers.
