An EAS RF antenna system is a retail security system that uses radio frequency (RF) technology to detect electronic tags on merchandise, triggering an alarm if an item leaves the store without the tag being deactivated. These systems are commonly used in stores to deter theft by alerting staff to unauthorized removals through both visual and audible alarms. The “RF” in the name refers to the radio frequency technology used, which operates at around

MHz and is compatible with many types of tags and labels.
