Communications systems and methods for transmitting extendible conveyor control signals along an extendible conveyor. A conveyor communication system includes a first transceiver for use on a stationary boom of an extendible conveyor system, configured to communicate with a conveyor main control of the extendible conveyor system. The conveyor communication system includes a second transceiver for use at an end boom of the extendible conveyor system, configured to communicate with a control station on the end boom. The second transceiver is configured to receive wireless communications from the first transceiver over a wireless communications link.
