A lot people use the iTrip from Griffin Technology as a way to interface their iPod with their FM car stereos. In fact is a great wireless FM Transmitter. But the problem is that it has a very short range, and the signal starts breaking up very easily -- Just moving the ipod around your car can lead to static and complete sound fading. A few members at Spymac have come up with a great antenna hack for the iTrip. They are claiming that this mod increases the range to almost 60 feet, which should lead to much cleaner sound in your car.
I was sick and tired of how everytime I pulled up to a traffic light, my iTrip would cut out or hiss. I solved the problem.
1. First, i used a razorblade to pry the unit open.
2. Then, i got a paperclip and tightly wrapped a long section of copper wire around it like a spring.
3. After taking the copper wire off the paperclip, I slid it over the existing antenna, then with a section of heat shrink to seal it and you would not believe how much better it is.
4. Then I popped it back together, and now its AMAZING! I have no static in it at all now. and i can go over 60-70 feet away and it also makes the highs and the lows better.
I have taken pictures for an easier understanding in how it should be.

All smushed back together, now we just wait for the glue to dry up.
