Dongfeng KL truck parts GPS antenna assembly 7920030-C3300

Built for reliable GPS signal acquisition in complex environments, this antenna assembly features exceptional signal reception performance. Equipped with a ceramic patch radiator (25×25mm) and low-noise amplifier (LNA) with 28dB gain, it captures weak satellite signals even in urban canyons, mountainous areas, or dense forests—achieving a positioning accuracy of ±1m (CEP) under open sky conditions. The LNA’s noise figure of ≤1.5dB minimizes signal interference, while a built-in band-pass filter blocks out-of-band signals (e.g., 4G/5G interference) by 60dB. The antenna supports multi-constellation reception (GPS, GLONASS, Beidou), ensuring access to 20+ satellites simultaneously, which reduces positioning time to ≤30 seconds (cold start) and maintains stable tracking even during signal temporary interruptions

Engineered to withstand the harsh outdoor conditions of truck operation, the 7920030-C3300 antenna features a robust, weatherproof design. The housing is made of UV-stabilized ABS plastic (UL94 V-0 grade) with a 5mm wall thickness, achieving an IP67 protection rating—resisting dust ingress and water submersion up to 1m for 30 minutes. The SMA connector is sealed with HNBR rubber, preventing water and corrosion from affecting signal transmission. The antenna operates stably in extreme temperatures ranging from -40℃ to 85℃, adapting to frigid northern winters and sun-exposed roof surfaces. It also resists vibration (10-500Hz) and impact (10kJ/m²), enduring road bumps and accidental collisions with branches or debris without performance degradation

Optimized to integrate seamlessly with the Dongfeng KL’s electrical system, the antenna assembly features low-power consumption and anti-interference capabilities. The LNA operates at 3.3V DC with a current draw of only 15mA, minimizing power consumption and avoiding overloading the vehicle’s 12V electrical system. The RG-58 coaxial cable is shielded with tinned copper braid (95% coverage) and aluminum foil, reducing electromagnetic interference (EMI) from the truck’s engine, alternator, and communication systems by 80%. This shielding ensures the GPS signal remains pure, preventing positioning drift that could lead to route errors (costing $500+ in delayed deliveries). The antenna also complies with automotive EMC standards (ISO 11452), avoiding interference with other on-board electronics

This GPS antenna assembly is designed for efficient deployment and long-term cost savings for Dongfeng KL operators. The integrated magnetic base (pull force ≥5kg) allows tool-free temporary installation, while the optional bolt-on mounting kit enables permanent fixation on the cab roof or rear panel—completed by a single technician in 20 minutes. The 3m coaxial cable provides flexible routing to the navigation system, avoiding cable stretching or kinking. The OE-compatible design eliminates compatibility issues common with aftermarket antennas, which often cause navigation system failures (repair costs up to $400). By ensuring stable positioning, it enhances fleet management efficiency—enabling real-time tracking, route optimization, and fuel consumption monitoring. With a service life of ≥300,000km and 2-year/200,000km Dongfeng warranty, it provides reliable performance and predictable maintenance expenses
