transmitter
Device broadcasting waves
A transmitter is a device that sends signals—radio waves, electrical impulses, or other forms of energy—from one point to another.
Radio and television stations use transmitters to broadcast programming.
In biology, a neurotransmitter is a chemical that carries signals between nerve cells.
More loosely, anything that passes something along is a transmitter: a transmitter of disease, a transmitter of cultural values.
