1. A tunable EAS system, comprising:

  • at least one antenna;

    a controller circuit board for each said antenna, each controller circuit board having WiFi capabilities allowing each said controller circuit board to wirelessly connect to the same central computer, each said controller circuit board comprising a controller executing machine readable instructions, each said controller circuit board being powered by alternating current;

    each said controller circuit board operating its respective antenna as a transmitting antenna to generate an interrogation field and as a receiving antenna to detect the ambient electromagnetic noise profile for its antenna and to detect EAS tags in its interrogation field;

    each said controller circuit board transmitting its own interrogation field cycle, the ambient electromagnetic noise profile detected by its respective antenna, and the zero crossing reference for its AC power supply to the central computer;

    each said controller circuit board being tunable from the central computer for optimized performance in its ambient electromagnetic noise profile and with all other EAS antennas in the tunable EAS system.
