In this DIY tutorial, we are demonstrating an AM Loop Antenna in detail. It enhances all feeble AM signals thus improving faint radio signals. So, every nearby station can be heard over your AM radio dial. Amplitude Modulation (AM) radio recipients can utilize an assortment of receiving wire designs.
Additionally, this easy and simple circuit structure can beat different AM antenna styles. Moreover, it is an economical method to expand the scope of most AM radios. The radio ought to have two receiving wire lead screws – positive and negative. However, the casing can be opened for access to the circuit board if outside leads are absent. The normal radio professional can make a level loop antenna in around 30 minutes. This article will describe the issue, and how to make your loop antenna easily with next to no specialized skills.

Circuit Diagram
Circuit Operation
An Amplitude Modulation (AM) loop antenna can extraordinarily improve the AM radio reception. The circuit referenced above is a design of the AM loop reception apparatus. It will enormously improve the sensitivity of an AM radio. You don’t need to make any wire association with this receiving wire.
Therefore, to build this antenna use #35 enameled copper wire. Then, wound 16 turns on a square. Estimate 15inches on a side and 1.5 inches wide. Hence. this loop antenna will greatly help to cover the full AM standard communicated band from 550-1700 kHz.
Applications and Uses
An AM loop antenna is used to improve the Amplitude Modulation (AM) radio reception. It also helps to improve the sensitivity of AM radios.
