Dongfeng KR truck parts 4G GPS antenna assembly 7920030-C51T0

Built to deliver reliable GPS positioning and 4G communication even in harsh signal environments, the antenna features a high-gain design. The GPS module achieves a tracking sensitivity of -165dBm and a positioning accuracy of ±1m (CEP), enabling real-time fleet tracking in urban canyons, tunnels, and remote mountainous areas. The 4G LTE module boasts a maximum gain of 9dBi, supporting download speeds up to 150Mbps and upload speeds up to 50Mbps—facilitating instant transmission of vehicle data (fuel consumption, mileage, fault codes) to the IFMS. A built-in low-noise amplifier (LNA) with 28dB gain reduces signal interference by 40%, ensuring stable connections even in areas with weak 4G signals (-115dBm)

Engineered for the outdoor operating conditions of commercial trucks, the antenna assembly exhibits exceptional weather resistance and durability. The antenna housing is made of UV-stabilized ABS+PC alloy (UL94 V-0 flame-retardant rating) with an IP68 waterproof/dustproof rating—preventing water intrusion even in heavy rain or high-pressure washing. The coaxial cable uses a double-shielded design (aluminum foil + braided copper) with a PVC jacket, resisting oil, chemical corrosion, and UV aging. It operates stably in a wide temperature range (-40℃ to 85℃), adapting to northeast China’s frigid winters and southwest China’s hot summers. The antenna undergoes 1000-hour salt spray testing (ASTM B117) and 500-hour UV testing, ensuring no performance degradation for ≥300,000km

Optimized for flexible installation and efficient fleet maintenance, the antenna supports three mounting methods: magnetic base, adhesive tape, and bolt fixing. The magnetic base (10kg pull force) enables tool-free temporary installation for testing, while the 3M VHB adhesive tape provides permanent bonding (shear strength ≥15MPa) to the truck’s roof or windshield. For heavy-duty scenarios, M4 bolts secure the antenna to the original bracket, preventing detachment during off-road driving. The 3m coaxial cable with a pre-formed 90° connector allows easy routing through the cab’s weatherstripping, avoiding wire damage. A single technician can complete installation in 20 minutes—60% faster than non-OE antennas requiring custom mounting

The antenna assembly integrates anti-interference technologies and fleet-specific functions to maximize operational value. A built-in band-stop filter suppresses interference from the truck’s engine, alternator, and radio systems, ensuring GPS positioning stability (positioning refresh rate: 1Hz). It supports Beidou/GPS dual-mode positioning, automatically switching to Beidou when GPS signals are blocked—critical for fleet operations in areas with GPS jamming. The 4G module is compatible with both public and private LTE networks, enabling secure data transmission for sensitive cargo (e.g., hazardous goods). Each antenna is pre-calibrated at the factory, requiring no on-site tuning, and comes with a 1-year warranty. Its reliable performance ensures accurate fleet scheduling, reduces fuel theft, and supports compliance with transportation regulatory requirements
