Product Advantages:  

By leveraging the high magnetic permeability of the ferrite core, it "concentrates" low-frequency magnetic field signals in space, enhancing the coupling efficiency between the coil and the magnetic field (ordinary air-core coils would require a larger volume to achieve the same coupling effect).  

Compared to traditional air-core coil antennas and whip antennas (used for high frequencies), the ferrite rod antenna offers irreplaceable advantages in its applicable scenarios (low-frequency bands, compact devices).  

Applicable Industries:  

Consumer electronics, security/identification, smart home portable AM radios, and more.
