We don’t just sell components. We partner with engineers like you to design and manufacture the perfect ferrite rod antenna for your product’s success.
As an engineer, you know a simple component can make or break the user experience. Unstable reception, noise interference, and poor sensitivity often trace back to a single, crucial part: the AM loopstick antenna.
At JHCOILS, we live and breathe magnetics. With over 15 years of specialized experience in custom coil winding, we understand the physics behind a great signal. Let us help you eliminate guesswork and build a reliable, high-performance “heart” for your product’s receiver.
AM Loopstick Coil
Off-the-shelf won’t cut it? We get it. At JHCOILS, custom is our standard. We transform your drawings, parameters, or even just an idea into a perfectly matched AM loopstick antenna, ready for production.
Your challenge is our next project. Give us your specs, and we’ll handle the rest.
Calculate tuning capacitance from known inductance and a target frequency. Then check the ideal frequency range of a variable capacitor.

The reliability of our AM loopstick antennas makes them a trusted component across a diverse spectrum of applications. They are at the heart of consumer electronics, delivering the crystal-clear audio demanded by high-fidelity tuners and retro audio systems. In the automotive sector, they ensure stable, uninterrupted reception for car radios on the move. Beyond entertainment, they form the critical backbone for industrial and IoT applications in low-frequency data transceivers, RFID, and positioning systems, while also serving as a foundational component for educational kits and radio enthusiasts.
Standard antennas offer a general-purpose solution. A custom antenna from JHCOILS is engineered precisely for your circuit. We tune the inductance to match your variable capacitor, optimize the Q-factor for your desired bandwidth, and use materials (like Litz wire) to maximize performance, resulting in superior sensitivity and clarity for your end product.
Our main manufacturing facility is located in China, which allows us to provide competitive pricing and large-scale production. However, our business is global. We have extensive experience with international logistics and regularly ship to our clients in North America (USA, Canada), Europe (Germany, UK, France), and across Asia. We handle all the complexities to ensure a smooth delivery to your door.
It’s a collaborative process. 1) You send us your specs (or problem). 2) Our engineers review and propose a design, often providing a technical drawing for approval. 3) We produce and send prototypes for your evaluation. 4) Once approved, we move to mass production with rigorous quality control at every stage.
Our MOQ is flexible and depends on the complexity of the custom antenna. We are committed to supporting projects of all sizes, from initial prototype runs (small batches) to high-volume mass production (millions of units). Please contact us with your project details, and we’ll provide a specific answer.
