Definition: RC vehicles communicate through radio signals. The transmitter antenna is a part of the radio system through which those signals travel. The transmitter antenna is a part of the handheld transmitter or controller that sends messages to the receiver antenna on the RC.
The transmitter antenna might be a solid metal tube or a piece of flexible wire with an end cap (which may or may not retract into the controller) or a telescoping antenna where the sections nest inside each other when collapsed. With some radios you'll need to screw the antenna into the controller.
