Since our inception, we've had our own manufacturing facility. Initially, our production line could only produce signal generators for RF jammers. However, with years of investment, we’ve developed a complete production line, handling everything from manufacturing to testing in-house. By controlling the entire production process, we can ensure the highest product quality. This commitment to quality is why our clients continue to choose us.

Today, we also offer OEM customization services, manufacturing products based on our clients' designs and requirements. Our R&D team is available to help clients evaluate their design plans, leveraging our years of industry experience to ensure their success.
