Perhaps it is not a 2:1 "balun" but a 2:1 transformer that is desired.

The impedance is stepped by the square of the turns ratio.

2:1 turns ratio gives 4:1 step.  If you want a 2:1 step, use 1.414:1 and you
will be close.

Try 14 turns and 10 turns.  or 7 and 5, etc. on a toroid.  Test the number
of turns to ensure you are getting good coefficient of coupling between
primary and secondary.  Too many turns and you have a choke.  Cut and
try....

Good luck.
