This product is an 869.25MHz dedicated low-frequency steel blade antenna, precisely tuned and optimized for the low-frequency IoT dedicated frequency band. It offers high frequency matching accuracy, stable impedance, excellent low-frequency signal receiving sensitivity, strong penetration capability, and good diffraction performance. Compared to conventional high-frequency antennas, it is better suited for long-distance data transmission in complex, obstructed environments—effectively resolving common low-frequency communication issues such as weak signals, short transmission distances, and frequent disconnections, ensuring stable data transmission without packet loss.

The antenna uses a precision steel blade radiating element with a thin, lightweight, and neat structure, offering sufficient toughness, resistance to deformation, and consistent frequency band parameters for stable batch quality. The overall structure is formed through an integrated bracket hot-melt curing process, with full and tight hot-melt filling that securely fixes the steel blade antenna to the bracket—eliminating internal looseness, shifting, and rattling. With vibration resistance, drop resistance, and jolt resistance, its structural stability far exceeds that of ordinary adhesive assembly processes.
