Narrative:

I was working radar satellite position south at orlando international TRACON. I had traffic landing mlb airport at 3000 ft so I kept a west wind also landing mlb at 2000 ft. The MVA in this area is mostly 1600 ft so I was unaware that by doing this; the west wind was heading toward the proximity of a 2000 ft antenna. Furthermore; the low altitude alert never alarmed so I was never alerted that there might have been a problem. Had a low altitude alarm alerted me I would have taken evasive action. Also some type of visual reminder depicting the ht of that obstacle would have helped.

Title: MCO CTLR EXPERIENCED OPERROR WHEN VECTORING ARR TFC BELOW MVA.

Narrative: I WAS WORKING RADAR SATELLITE POS S AT ORLANDO INTL TRACON. I HAD TFC LNDG MLB ARPT AT 3000 FT SO I KEPT A WEST WIND ALSO LNDG MLB AT 2000 FT. THE MVA IN THIS AREA IS MOSTLY 1600 FT SO I WAS UNAWARE THAT BY DOING THIS; THE WEST WIND WAS HDG TOWARD THE PROX OF A 2000 FT ANTENNA. FURTHERMORE; THE LOW ALT ALERT NEVER ALARMED SO I WAS NEVER ALERTED THAT THERE MIGHT HAVE BEEN A PROB. HAD A LOW ALT ALARM ALERTED ME I WOULD HAVE TAKEN EVASIVE ACTION. ALSO SOME TYPE OF VISUAL REMINDER DEPICTING THE HT OF THAT OBSTACLE WOULD HAVE HELPED.
