# SIMCONNECT_DATA_FACILITY_NDB The **SIMCONNECT\_DATA\_FACILITY\_NDB** structure is used to return information on a single {{< glossterm >}}ndb{{< /glossterm >}} station in the facilities cache.   ##### Syntax ``` cpp struct SIMCONNECT_DATA_FACILITY_NDB : public SIMCONNECT_DATA_FACILITY_WAYPOINT{ DWORD fFrequency; }; ```   ##### Members {{< table-wrapper >}} | Member | Description | |--------------|---------------------------------| | `fFrequency` | Frequency of the station in Hz. | {{< /table-wrapper >}}   ##### Remarks This structure is returned as one element in the [SIMCONNECT\_RECV\_NDB\_LIST](simconnect-recv-ndb-list/) structure. It inherits all the members of the [SIMCONNECT\_DATA\_FACILITY\_WAYPOINT](simconnect-data-facility-waypoint/) structure.   See the remarks for [SimConnect\_RequestFacilitesList](../facilities/simconnect-requestfaciliteslist/).
