Shenzhen Haiyi Technology Electronics Co., Ltd. was founded in 2014. We are a high-tech company centered in researching and development, manufacturing of high-performance wireless communication technology products, especially in the shortwave (HF), ultra shortwave (VHF, UHF), radio frequency (RF), and microwave (MW) frequency bands (covering the range of 20MHz to 6000MHz), including but not limited to narrow band, broadband, linear, high gain, high-power, and low-power models. All products have passed reliability testing.
We are a manufacturer focus on developing and producing drone countermeasure equipment independently for air safety and privacy under legal permission. This device is designed to interfere and block satellite positioning signals, including GPS / Beidou / GLONASS / Galileo. Meanwhile, it can interfere and shield the commonly used ISM 2.4G and ISM 5.8G frequency bands for drones, forcing remote control, image transmission positioning, and signal interruption, achieving the functions of forced landing / return / hovering.
Our main products are signal amplifiers, radio frequency power amplifier modules, wireless signal control systems, wireless signal countermeasures, wireless signal blocking devices, and explosion-proof interference devices. Our products are widely used in communication, scientific research institutions, special field communication RF modules, communication signal coverage systems, professional measurement equipment, and electronic countermeasures.
We have a professional and experienced R&D team to provide our clients with excellent competitiveness of communication products and technical support. After 10 years of continuous development and growth, Haiyi has won a good reputation with reliable product quality, on-time delivery, self-produced and self-marketing cost advantages, as well as good after-sales service. Our products are exported to the United States, Russia, the Middle East, Africa and other countries and regions. We sincerely welcome customers domestic and overseas to contact us and establish a long-tern business partnership.
