Narrative:

We were working the midnight shift at atl ARTCC combined on 1 sector. I was conducting OJT on the r-sides. There were only 3 aircraft on the scope. My trnee descended air carrier X to 2000' while on a vector to the final approach course for an ILS approach. The minimum vectoring altitude for this area is 2900'. The aircraft passed in close proximity to a radio or tv antenna which is 1900' MSL. I informed the area manager of the incident. The MSAW alert did not go off. The antenna is not depicted on the radar scope. I consider fatigue to be a significant factor in this incident.

Narrative: WE WERE WORKING THE MIDNIGHT SHIFT AT ATL ARTCC COMBINED ON 1 SECTOR. I WAS CONDUCTING OJT ON THE R-SIDES. THERE WERE ONLY 3 ACFT ON THE SCOPE. MY TRNEE DSNDED ACR X TO 2000' WHILE ON A VECTOR TO THE FINAL APCH COURSE FOR AN ILS APCH. THE MINIMUM VECTORING ALT FOR THIS AREA IS 2900'. THE ACFT PASSED IN CLOSE PROX TO A RADIO OR TV ANTENNA WHICH IS 1900' MSL. I INFORMED THE AREA MGR OF THE INCIDENT. THE MSAW ALERT DID NOT GO OFF. THE ANTENNA IS NOT DEPICTED ON THE RADAR SCOPE. I CONSIDER FATIGUE TO BE A SIGNIFICANT FACTOR IN THIS INCIDENT.
