Designing a GSM monopole to dipole transformer

Hello guys,
I am currently making a design including a GSM module which has a 50 ohm impedance output for the antenna. However I am interested in using a dipole (73 Ohm img 43Ohm) antenna with this module.
I have been searching around for either a dedicated , or discrete balun that can handle this transformation, with no luck.
Does anybody have any knowledge on how to design one, or where to look for such a design?
Best regards
Nikolaj
