The QS2000's expansion piece.
The QS2000 single is most commonly found in its digital (board-based) form. It's used alongside a QS2000 dual-antenna setup to extend detection width — three QS2000 antennas can cover a 6-ft door, and two can cover a 3-ft door.
The expansion antenna is primarily a receiver (Rx) board; a transmitter (Tx) board can be added when needed by slaving the two transmitters together. Commonly seen in Walgreens installs. Like the dual system, the QS2000 can be tuned to 8.2 or 9.5 MHz — 8.2 being the dominant RF EAS frequency.
