Abstract: A radio frequency waveguide communication system includes a controller configured to output a radio frequency signal, and at least one connected node configured to output a node signal indicative of monitored parameter of a machine. The radio frequency waveguide communication system includes a waveguide and a radio frequency interface module. The waveguide is in signal communication with the controller and is configured to guide the radio frequency signal toward the at least one connected node. The radio frequency interface module is configured to establish signal communication between the controller and the at least one connected node, and includes at least one detachable portion configured to detach from the at least one waveguide.
