Answer​​:
The CK-A11 UHF RFID Reader Antenna is engineered to tackle high-density RFID environments like retail shelves or warehouse inventory racks. Its ​​11dBi high gain​​ ensures a read range of up to 3 meters, while the ​​85° horizontal beamwidth (H-plane)​​ provides wide coverage to scan multiple tags simultaneously. For optimal performance:

• ​​Circular Polarization​​: Reduces signal reflection and tag orientation dependency, critical for items stacked at varying angles.
• ​​Low VSWR (≤1.3:1)​​: Minimizes signal loss, ensuring consistent reads even in congested setups with metal shelves or electronics.
• ​​IP65 Protection​​: Safeguards against dust and accidental spills during inventory audits.

Pair the CK-A11 with UHF RFID readers supporting ​​ISO 18000-6C protocols​​ for seamless integration into systems like SAP or custom WMS. Its ​​340mm×198mm slim profile​​ allows flexible mounting on shelves, walls, or poles without obstructing workflows.

​Answer​​:
Yes! The CK-A11 is built to thrive in challenging industrial settings with metal interference. Key features include:

• ​​Anti-Material Design​​: The ​​aluminum backplate​​ and ABS housing minimize electromagnetic interference (EMI) from nearby machinery or metal structures.
• ​​Wide Frequency Range (840-960MHz)​​: Adapts to regional UHF bands and avoids clashes with industrial equipment operating in the 900MHz spectrum.
• ​​Robust Construction​​: With a ​​-40°C to +85°C operating range​​, it withstands temperature fluctuations in factories, cold storage, or outdoor yards.

For best results in metal-rich areas:

• Position the antenna ​​0.5-1 meter away from large metal surfaces​​ to reduce reflection.
• Use ​​N-type connectors​​ and high-quality coaxial cables to maintain signal integrity.
• Pair with ​​anti-metal RFID tags​​ for direct placement on steel assets like tools or pallets.

​​3. What Makes the CK-A11 Ideal for Global Logistics and Cross-Regional RFID Deployments?​​

​​Answer​​:
The CK-A11’s ​​840-960MHz ultra-wide frequency band​​ ensures compliance with UHF RFID regulations worldwide:

• ​​EMEA (865-868MHz)​​, ​​FCC (902-928MHz)​​, and ​​APAC (920-925MHz)​​: A single antenna works across regions, eliminating the need for region-specific hardware.
• ​​Circular Polarization​​: Compensates for signal polarization mismatches in fast-moving logistics scenarios, such as conveyor belts or forklift-mounted readers.
• ​​Lightweight & Portable​​: At ​​850g​​, it’s easy to deploy in temporary setups like pop-up distribution centers or vehicle-mounted RFID systems.

For logistics applications:

• Combine with ​​4G/WiFi-enabled RFID readers​​ for real-time tracking updates.
• Use the ​​IP65 rating​​ to protect against rain, dust, or humidity during outdoor operations.
• Leverage its ​​70° vertical beamwidth (E-plane)​​ to focus signals on tagged items in loading docks or shipping containers.
