Narrative:
Air carrier X had been cleared to land runway 33. While turning base the pilot informed me that they needed to burn fuel. I decided to give a vector to the south east with an altitude of 3;400 ft. Ten miles south east of our airport antennas require an MVA of 4;400 ft. I thought the turn was far enough to have missed the antennas and didn't climb the aircraft to the MVA. Once I shipped the aircraft to departure I realized that the aircraft was within the 3 miles needed for separation. Review MVA's and be aware of airspace outside the class D.
