Controller reported an Associate vectored a departure aircraft into an antenna farm at a low altitude.

Narrative

At the time of the event I was CIC and working the satellite radar position in the TRACON. The aircraft departed ZZZ airport on a 180 heading. Upon contacting departure the aircraft was instructed to climb to his final altitude and proceed on course to ZZZ1. The antennae approximately 7 southwest of the airport reach an altitude of 2;048 MSL. The MVA surrounding these antennae is 3;000 MSL. The aircraft made a left turn and slowly climbed. About 2 miles from the antennae the MSAW started going off with a low altitude alert. I believe the aircraft was at 1;900 MSL (still below the highest antenna). The Controller working Departures recognized at this point and told the aircraft to expedite his climb. To which he responded we have the antenna in sight. About 1 mile from the antennae; the aircraft was still only at 2;000 FT MSL. The weather was IFR but knowing the aircraft was a slow climber the Controller should not have issued a turn. I do not believe weather was a factor. The Pilot never reported a problem; but an operational error had occurred. I would recommend re-training this Controller on the effects an antennae farm being so close to an airport has on arrivals and departures. I would also suggest re-training on the rules of vectoring below the MVA.
