Non–Directional Beacon Receiver
Non-directional beacon monitor/arlarm receiver is used to receive signal of NDB transmitter located at NDB Landing station or NDB Enroute station. Purpose to serve the air traffic controller or relevant people in monitoring continuously the operation of the stations in the civil flight operations. The receiver manufactured by Air Traffic Technical Company Limited, is a kind of dedicated radio receiver, working at long wave (wavelength m) with the high sensitivity and selectivity, easy operation. The receiver operates stably in different environmental conditions.
