 Lance,

There are designs on the internet for big resonant loop antennas for AM radios with small internal ferrite loop antennas. They improve signal levels by coupling a larger antenna to the internal one by proximity. The large loop is a coil that is connected to a capacitor that tunes to the center of the radio band. The small radio gets more signal to overcome the noise by being near the larger loop antenna.
