My first thoughts are you will need to cut it in half to separate it into
the two poles of the dipole.  Then you will need to lengthen it a little.
Chances are you will just need to add a little to the poles inside the traps
as opposed to the outside traps.  

Good luck, I hope you get it working well and soon.
