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.
