The CK-A3 is built for busy warehouse environments where pallets are stacked tight and metal shelves mess with RF signals. Its 70° beam gives broad coverage, so it can pick up lots of tags at once, and the circular polarization helps keep reads stable even when metal is everywhere. In most setups, you can expect clean reads out to around five meters.

For best results, mount it at around three to four meters high and angle it slightly down so it “sees” the shelves clearly. Pairing it with a high-power reader like the CK-R4 pushes the system to very high tag counts per second. The low VSWR helps keep the signal steady, and if you’re working in cold storage, the wide temperature range makes it a worry-free option.

Circular polarization keeps things simple in places where tags are always moving or sitting at odd angles. You don’t need to worry about matching tag orientation—AGVs, conveyor belts, hand-placed items, all get picked up reliably. It also handles reflections better, which is a big win around metal machines and steel racks.

The CK-A3 combines solid gain with a tight axial ratio, giving a very even field. That helps in automotive lines with metal-heavy parts and in retail shelves packed with small items. If you’re using it outdoors or in rough sites, pair it with durable RFID tags so the whole chain stays reliable.

The CK-A3 covers the full 840–960MHz range, so it works across EU, US, and Asia RFID bands without needing region-specific hardware. It’s tuned to stay efficient across all these ranges, keeping VSWR low so power isn’t wasted.

It supports the major global RFID protocols, which makes integrating it into mixed-region systems easier. For companies running operations in multiple countries—from the Gulf to Europe—using the same antenna everywhere keeps deployment simple and consistent.
