GPS Antenna Assembly TBOX OE 7920030-C33T0 for Dongfeng KL Truck

This GPS antenna assembly is precision-engineered to match the original equipment standards of Dongfeng KL trucks, featuring the OE number 7920030-C33T0 for guaranteed compatibility. It integrates perfectly with the truck’s existing TBOX system, requiring no wiring modifications or additional adapters—simply plug into the factory interface to restore full positioning functionality. Compatible with all Dongfeng KL series models, including tractor-trailers and cargo trucks, it eliminates fitment risks for fleet operators and repair shops. The design adheres to the vehicle’s electronic specifications, ensuring no interference with other on-board systems while maintaining optimal performance. Whether replacing a faulty unit or upgrading a fleet, this antenna offers a hassle-free solution that aligns with OEM quality standards.

Equipped with advanced ceramic patch antenna technology, this component delivers exceptional signal sensitivity (≤-140dBm) and fast satellite acquisition, enabling real-time positioning accuracy within ±2 meters. The built-in low-noise amplifier (LNA) with 28dB gain enhances signal strength, ensuring reliable connectivity even in challenging environments such as remote highways, tunnels, or dense urban canyons. Operating on the GPS L1 band (1575.42MHz), it supports multi-satellite reception for consistent performance, minimizing signal dropouts during long-haul trips. This level of precision is critical for fleet management, enabling accurate route tracking, mileage calculation, and vehicle security monitoring. For logistics companies, the stable signal transmission ensures timely data sync with fleet management software, facilitating data-driven decision-making to improve operational efficiency.

Built to withstand the rigors of heavy-duty truck operations, this GPS antenna assembly features a weather-resistant ABS plastic housing and IP67 waterproof rating, protecting against water, dust, and debris. It tolerates extreme temperatures ranging from -40°C to +85°C, making it suitable for use in diverse climates—from cold northern regions to hot desert areas. The 1.5m coaxial cable is wrapped in a wear-resistant jacket, resisting abrasion and UV damage for long-term reliability. Rigorous testing, including salt spray, vibration, and impact resistance, confirms its durability in harsh road conditions. Unlike low-quality alternatives, this antenna maintains performance over time, reducing the need for frequent replacements and lowering total cost of ownership for truck owners and fleet managers.

Designed for efficiency, this GPS antenna assembly comes with a high-strength adhesive mounting base that attaches securely to the truck’s roof or dashboard, ensuring a stable fit even at high speeds. The plug-and-play connector matches the factory TBOX interface, allowing technicians to complete installation in less than 15 minutes—no specialized tools or technical expertise required. Once installed, the antenna operates maintenance-free: its solid-state design has no moving parts, and the corrosion-resistant components ensure long service life. The compact, lightweight design (0.3kg) minimizes wind resistance and does not affect the truck’s aerodynamics, making it suitable for all driving conditions. For fleet managers, the easy installation and zero-maintenance operation reduce downtime and labor costs, ensuring trucks spend more time on the road and less in the shop.
