Abstract
Automatic tuning of an EAS antenna pedestal without the use of special tools or advanced training is provided. The capacitance of the antenna circuit is adjusted to tune the resonant frequency to the desired frequency. Measurement of the current level is used to validate that the antenna is resonant at the desired frequency. If the current level indicates that the antenna is not resonant at the specified frequency, LEDs located on a capacitor tuning board light to indicate where jumpers should be placed to add or remove capacitance from the circuit. Alternately, the capacitance values can be electronically added or removed from the circuit.
