How can I improve the antenna of my FM modulator? Answered

I have a car (2003 Mitsubishi Galant) with the radio antenna embedded in the rear window.  I want to add an antenna to my FM modulator to improve the signal quality.  How can I determine the best antenna length and placement?

I already have information on how to mod the device. It's a Soundfeeder SF100.

And yes, this will become an Instructable eventually.  :-)

.  Just about any antenna designed for FM (88-108MHz) use will work. The problem will be in figuring out how to mod the SF100 to accept an external antenna.

Thanks!  I suspected that would be the case.

I've got the actual modding part covered, thanks to someone called "jdacura".

This is funny! Though I don't think it will fit in a car!

 This is what my husband did - http://drupal.brainstomp.net/?q=node/10 to hack a Monster iCarPlay in the same manner.
