As a kind of medium frequency radio navigation equipment, the NDB-500 non-directional beacon can be used as a navigation aid in airport, airway, and maritime or land oil platform. It is mainly composed of three components that are the main unit, automatic antenna tuner and remote control unit.

There are two identical channels in one unit of the non-directional beacon. When one of the channels is broken, it would automatically switch to another. The function of unattended remote control and monitor of the NDB-500 non-directional beacon is available with the help of a two-wire connection. All of our product's performance meet the applicable requirement of ICAO Annex 10.

The non-directional beacon provides mutual backup for the two identical channels in one unit. The switch between the two channels is also automatic. The unattended remote control and monitor of the NDB-500 non-directional beacon is achieved through a two-wire connection. All of its technical performances meet the applicable requirements of ICAO Annex 10.
