A communication system is disclosed. The system can include a first communication unit including a first antenna, a second communication unit including a second antenna and a dielectric waveguide cable, and a rotary joint configured to enable the first unit to rotate with respect to the second unit about an axis of rotation of the system. The dielectric waveguide cable can extend from the second antenna to the rotary joint, where a proximal end of the cable can be coupled to the second antenna and a distal end of the cable can be affixed to the second unit at a location bordering a space defined by the rotary joint. The first and second units can be configured to engage in two-way communication with each other. An axis of the distal end of the cable can be substantially aligned with the axis of rotation of the system.
