Narrative:

I was working approach control; vectoring aircraft X on extended vectors for an opposite direction practice ILS approach; awaiting a departure to get airborne. When I saw that aircraft X who was going extremely fast on his vector was getting close to an obstruction I turned him to avoid the obstruction clearance ring and he barely clipped the ring itself due to his wide turning. The minimum vectoring altitude over the obstruction is 2;300 ft and aircraft X was at 2;000 ft and he was still 3 miles from the obstruction itself and higher than the obstruction. I should be quicker with turning a fast mover considering they make horribly wide turns.
