Ningbo Debiyi Technology Co., Ltd. (formerly Shanghai Erli Electronics) is a high-tech enterprise specializing in the R&D, production and global sales of HF/VHF/UHF full-band vehicle communication antennas, shortwave loaded antennas and supporting RF accessories. Located in Yuyao, Ningbo, we have established mature systems for antenna structural design, RF matching tuning, precision winding technology, material selection and mass production quality control. We supply high-performance and highly stable RF antenna products for radio enthusiasts, vehicle communication industry and outdoor emergency communication sectors worldwide.

        We focus on core technologies of shortened loaded shortwave antennas. We are proficient in the design principles of bottom-loaded, middle-loaded and top-loaded antennas, as well as key processes including multi-band impedance matching, SWR optimization, current distribution regulation and dual-band compatibility. Relying on self-developed winding specifications, standardized RF calibration systems and high-temperature & weather-resistant material solutions, we continuously optimize antenna radiation efficiency, communication range, bandwidth stability and high-power endurance. Our products are compatible with mainstream 10W–50W vehicle radios, covering full communication bands from 3.5MHz to 50MHz.

        Adhering to the philosophy of independent R&D, controllable quality and continuous upgrading, we implement full-process standardized production covering mandrel materials, conductor specifications, winding spacing, matching parameters and weather-resistant housing structures. We strictly control resonance accuracy, SWR stability, heat dissipation under high power and outdoor anti-aging performance, ensuring outstanding long-distance communication capability and strong adaptability to harsh vehicle operating environments.

        Our products are exported to Russia, Australia, Europe and many other regions around the world. We have gained long-term recognition from global customers thanks to reliable electrical performance, exquisite craftsmanship and professional technical support.

        In the future, we will keep advancing vehicle-mounted shortwave communication technology, focusing on multi-band composite antennas, high-efficiency loading structures and low-loss RF design. We will keep developing cost-effective and highly reliable communication antennas, striving to become an outstanding manufacturer and technology exporter in the global vehicle shortwave antenna industry.
