AM LOOP ANTENNAS


Posted on Oct 27, 2012

An AM loop antenna is one of the true marvels of electronics. Requiring no power, it takes advantage of the resonant properties of an inductor and a capacitor connected in parallel to receive weak AM stations. The `loop` part of the antenna is the inductor, and the tuning capacitor makes it resonate at a desired frequency.

As a boy in Abilene in 1967, I discovered the basic principle of the loop antenna. By removing a relatively small spiral loop in my five tube table radio, and substituting a much larger loop salvaged from an older radio, I could receive my favorite statio
