Wound on a 3 foot length of PVC pipe, the long loopstick antenna was an experiment to try to improve AM radio reception without using a long wire or ground. It works fairly well and greatly improved reception of a weak station 130 miles away. A longer rod antenna will probably work better if space…

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