Narrative:

On right downwind for runway 6 in bhm; we were cleared for the visual. Controller said 'watch for the antennas on the ridge.' we turned base looking left and right. We spotted some to our left. We were slightly above a normal descent angle. Suddenly; an antenna directly in front of us rose up and the terrain system stated 'obstacle.' we made an immediate right turn to avoid the antenna. The antenna was in the city lights. Had the controller pointed it out with a bearing and distance; we could have avoided the conflict. A passenger said 'thanks for missing the antenna!'
