Update...
I just went to the store and tested out the signal strength again. I counted off 150ft of reception! This compares to the old strength of 25ft. Also, I have a lot better AM/FM reception. A slightly thinner/longer wire might be even better reception. Don, what is your length? (You know what I mean). As I said earlier, I used about 15" in length. Ikarus pointed out that optimal antenna length is about 75cm (30"). I'm using half that and still get great reception. Ikarus also pointed out that the antenna was mainly for phone use. Here's a great physics q&a that I found. It explains it fairly well.
How do little tiny radios and walkmen pick up large radio waves without a visible antenna?
-- Emily Asher
Walkman radios use the cord that stretches from the radio to your head as a an antenna. FM radio stations emit at about 100 MHz which corresponds to waves with a wavelength about 3 meters long. Since the optimal antenna length is about 1/4 the wavelength the optimal antenna length is about 3/4 of a meter. Cell phones use much shorter wavelengths, about 1/3 of a meter, and so the antenna can be put into the phone itself since the optimal antenna length is less than 10 cm. -- S. Burkhart
PS. Thanks for all the "thanks" and I hope to see everyone use this mod. It is well worth it.
