Amplitude modulation (AM) radio receivers can use a variety of antenna designs, and one that offers superior reception is the loop antenna. This very simple design can outperform other styles, and is an inexpensive way to extend the range of most AM radios. The radio should have two antenna lead screws – positive and negative – but the casing can be opened for access to the circuit board if exterior leads are not present. The average radio technician can make a flat loop antenna in about 30 minutes. Tips Warnings Writer Bio
