Belkin TuneCast 3 Antenna mod...

Step 7: Fit the antenna...

Now, here comes the actual fun bit, fitting your new antenna!!! :D

Heat up your soldering iron, low heat again, and look for the BH1418FV chip, this is the FM transmitter, as Pin 12 of the chip is the RF-output, the resistors and attenuator are your enemy, therefore, you need to bypass these by soldering your antenna to the "C38" capacitor on the chip-side of the component, that's one part done. Next, take the other wire and solder it to where the other end of original red antenna was, and that's it, your new antenna is fitted!!!
