4G LTE Module High Gain Rubber Duck Antenna Signal Amplification FPV Drone Dedicated

丨 Product Introduction



Product Introduction：

AK448 is a high-performance PCB/FPC antenna optimized for 4G LTE applications. Leveraging proprietary technology, it delivers excellent performance across LTE Band 2/4/12 with high stability and sensitivity, ensuring efficient signal transmission and reception while complying with RoHS standards. Ideal for devices requiring stable multi-band 4G connectivity—especially North American market-targeted terminals like smart security cameras, in-vehicle smart terminals, industrial IoT devices, portable commercial terminals and smart utility devices—it meets the stringent requirements for long-term reliable communication in complex environments (see Figure 1 for details).


Features：

1. Multi band coverage: Supports LTE Band 2 (1850-1910MHz), Band 4 (1710-1750MHz), Band 12 (703-710MHz), meeting network requirements in North America and some regions.
2. High performance: Provides high TRP (transmission) and excellent TIS (reception) values in all supported frequency bands.
3. High reliability:Based on proprietary PCB&FPC technology, the performance is stable and consistent.
4. Compact structure:Exquisite size, easy to integrate in devices with limited space. 
5. Environmental compliance: Compliant with RoHS directive requirements.
