So we'll wait to hear from Alan and Al about what you should really do

As long as you stay under 3.2 miles, your low power transmitter is completely (edit: not) legal. You should be fine with adding an antenna to any of the commercial iPod FM transmitters. A few of them have ports for antennas ready to go.

You used to be able to purchase everything you'd need to do this at Radio Shack, but I don't think so now.

Be aware that FM sound quality will probably not be exactly what you're looking for if you can tell the difference between an MP3 and a CD, or other similarly degraded audio. Running wires or using a Wi-Fi solution would get you better results.
