Human Factors; Procedure
A BE20 was IFR inbound for the airport. Weather was low visibility but he had the weather and thought that he could get a Visual Approach. I gave him a pilot's discretion descent to 3;000 direct a fix which took him over an antenna with an MVA of 3;500. I had been relieved prior to this occurrence but I had issued the instructions. The MVA's had recently changed twice within the last few months and I knew that they were lower than before but simply made an error about it. This is the highest obstacle within the airspace. We have had many MVA errors because of it. I do not know what could be done to lessen controllers forgetting about this obstacle; or forgetting that it is higher than 3;000 FT.
TRACON Controller described a MVA non-compliance event when issuing a direct routing to a departure; failing to note the route went through a higher MVA.
