CK-A9 9 dBi antenna can read tags up to 10 m if installed right. Mount it vertically with the connector down to keep moisture out, and use the included pole bracket for stability. Keep it at least 30 cm from big metal objects, and tilt 25° up in metal-heavy areas to use its 56° vertical beam. Pair with regional UHF readers (865–868 MHz EU, 902–928 MHz FCC) and check VSWR stays under 1.3. For full coverage, set up 4+ antennas in a circle with 5 m spacing, which cuts dead zones by 70%. Done right, you can hit 99.5% read accuracy for pallet tracking in logistics hubs.

Yes, the CK-A9 works with Zebra and Impinj readers. Its 50 Ω impedance and N-type connector make integration easy. With Zebra FX9600/FX7500, use short LMR-400 cables and 30 dBm power for 8 m+ reads. With Impinj R700/R2000, turn on Dense Reader Mode and its <3 dB axial ratio supports FastID at 600 tags/sec. For Android or hybrid handhelds, add a WiFi/Bluetooth filter to cut interference. Its 840–960 MHz band covers EU, US, and China standards, so it works globally with ISO 18000-6C/6D systems.

CK-A9 is built for tough sites. It runs from –40°C to 85°C, and a heated radome option works down to –50°C. The ABS housing won’t get brittle in the cold. With IP65 protection, it handles water jets and dust, and the aluminum base resists acids and concrete splashes. For underground mining, use IP67 tags and place antennas at tunnel intersections for full 360° coverage of vehicles and tools.
