A long wire balun or should we say unun is a great help for converting

the
high impedance of a very long wire compared with frequency to an

impedance
that is much closer to 50 ohms....

========================

Only half right.

If the input impedance of a long wire is LESS THAN 50 ohms then a unun

makes
it worse.

If the input impedance of the wire is less than 50 ohms then either
1) it is not a long wire, it is a short wire,or
2) it is in intimate contact with the ground or counterpoise it is being
worked against;
if ground then it is a buried radial; if counterpoise then it's half a
transmission line.
