MIT Physics Demo -- Dipole Antenna

An RF transmitter is connected to a long antenna, emitting radio waves. A dipole antenna with a light bulb between its elements acts as the receiver. When the receiving antenna is parallel to the transmitter, the radio waves are absorbed, creating a current in the antenna and causing the bulb to glow. When perpendicular, no current is created, and the bulb does not glow.

Do you know where one can find that RF transmitter? We're looking to get one for ourselves.
