丨 Product Introduction
Product Introduction
The Dalang AK156 is a high-performance active ceramic antenna, engineered to deliver reliable positioning for vehicle, IoT, and wearable devices. It fully supports GPS L1 (1575.42MHz), BDS B1 (1561MHz), GLONASS L1, and GALILEO E1 frequency bands, integrating four global mainstream satellite navigation systems. Crafted with premium ceramic materials and adhering to industrial-grade standards, it combines compact design (25257.5mm, 12.8g) with exceptional performance, perfectly adapting to diverse application scenarios that demand precise and stable positioning.
Core Features
1.Multi-System Dual-Band Compatibility: Synchronously receives signals from GPS, BDS, GLONASS, and GALILEO, significantly improving positioning reliability and coverage, even in complex environments.
2.Superior Performance Metrics: Boasts 3dBic peak gain and <1.5dB low noise figure, with RHCP polarization and 50Ω impedance, ensuring strong signal reception and high positioning accuracy.
3.Strong Anti-Interference Capacity: Optimized radiation pattern effectively suppresses multipath and electromagnetic interference, maintaining stable performance in harsh electromagnetic environments.
4.Flexible Customization Options: Supports personalized configuration of cable length (standard 15cm), line type (RG1.13), and interface (IPEX) to meet diverse application needs.
5.Low Power & Durable Design: Operates at DC 2.7~3.3V with 3~6mA current, extending battery life of mobile devices; wide temperature resistance (-40℃～+85℃) adapts to harsh working conditions.
