Description
Overview
This 902-928 MHz Guardwall antenna provides a tightly controlled read zone and intense RF field penetrating deep into packed cases thus is ideal for item-level reading of packed goods. Used in pair, this antenna absorbs energy from its opposing mate so that very little passes beyond the exterior face. This combination maximizes stray read rejection by constraining the read zone to the area within the two antennas. It also increases read reliability by maximizing the intensity within the read zone. A pair of these antennas used together creates an intense, well-contained read zone.
Features
- Well-controlled read zone minimizes stray reads.
- Optimizd for reading item-level tags packed in cases.
- Designed for RoHS compliance.
