Ok let me see if I can do this from memory...
The wire strung from the top of the cabin to the tail= ADF antenna
Antenna's on the tail= VOR
Two identical antenna's on top=VHF (radio 1&2)
Antenna's on the bottom;
Little sharkfins= DME and transponder
Protruding rod= older style transponder
Oval half inch thick= ADF antenna
Depending on equipment, GPS antenna's on top.
Here's a hint, antenna's are usually marked with the manufacturer's name so if you look on the instrument panel.
If an antenna says Garmin it's the GPS.
