Narrative:

Departed gpm VFR to aus; runway 35 climbing right turn. Contacted regional approach around 2100 ft MSL; received squawk code. Proceeded VFR to south. Saw antenna farm ahead and climbed to avoid antennae. I inadvertently climbed into class B airspace. Controller noticed me above class B and asked my altitude. I said '4000 ft.' but my altimeter showed 3800 ft MSL. Controller ordered me to descend immediately to 2000 ft. I did so immediately; and had to take hard right turn to evade antennae; which were about 3000 ft MSL. Cause of problem: I did not pay attention to my altitude. Prevention: I should have put the class B floor altitude into my system; to help keep me clear of class B airspace.
