A balun work's best when it see's a pure resistance, or nearly so.  A
balun at the end of a piece of coax, feeding a length of balanced line
that feeds an antenna, will almost be guaranteed to see a reactive load.

A better idea would be to place the balun at the input of a balanced
tuner.  If there are difficulties in bringing in the balanced line to
the tuner, then a small section of shielded balanced line can be
employed.
